5d170fe435 f2fs-for-6.1-rc1 
This round looks fairly small comparing to the previous updates which includes
 mostly minor bug fixes. Nevertheless, as we've still interested in improving
 the stability, Chao added some debugging methods to diagnoze subtle runtime
 inconsistency problem.
 
 Enhancement
  - store all the corruption or failure reasons in superblock
  - detect meta inode, summary info, and block address inconsistency
  - increase the limit for reserve_root for low-end devices
  - add the number of compressed IO in iostat
 
 Bug fix
  - DIO write fix for zoned devices
  - do out-of-place writes for cold files
  - fix some stat updates (FS_CP_DATA_IO, dirty page count)
  - fix race condition on setting FI_NO_EXTENT flag
  - fix data races when freezing super
  - fix wrong continue condition check in GC
  - do not allow ATGC for LFS mode
 
 In addition, there're some code enhancement and clean-ups as usual.

4875d2ffb0 gfs2 fixes 
- Make sure to initialize the filesystem work queues before registering
   the filesystem; this prevents them from being used uninitialized.
 
 - On filesystem withdraw: prevent a a double iput() and immediately
   reject pending locking requests that can no longer succeed.
 
 - Use TRY lock in gfs2_inode_lookup() to prevent a rare glock hang
   during evict.
 
 - During filesystem mount, explicitly make sure that the sb_bsize and
   sb_bsize_shift super block fields are consistent with each other.
   This prevents messy error messages during fuzz testing.
 
 - Switch from strlcpy to strscpy.

 - Also the Maple Tree from Liam R.  Howlett.  An overlapping range-based
   tree for vmas.  It it apparently slight more efficient in its own right,
   but is mainly targeted at enabling work to reduce mmap_lock contention.
 
   Liam has identified a number of other tree users in the kernel which

   This has yet to be addressed due to Liam's unfortunately timed
   vacation.  He is now back and we'll get this fixed up.
 
 - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer.  It uses
   clang-generated instrumentation to detect used-unintialized bugs down to
   the single bit level.
 
   KMSAN keeps finding bugs.  New ones, as well as the legacy ones.
 
 - Yang Shi adds a userspace mechanism (madvise) to induce a collapse of

d4013bc4d4 bitmap patches for v6.1-rc1 
From Phil Auld:
 drivers/base: Fix unsigned comparison to -1 in CPUMAP_FILE_MAX_BYTES
 
 From me:
 cpumask: cleanup nr_cpu_ids vs nr_cpumask_bits mess
 
 This series cleans that mess and adds new config FORCE_NR_CPUS that
 allows to optimize cpumask subsystem if the number of CPUs is known
 at compile-time.
 
 From me:
 lib: optimize find_bit() functions
 
 Reworks find_bit() functions based on new FIND_{FIRST,NEXT}_BIT() macros.
 
 From me:
 lib/find: add find_nth_bit()
 
 Adds find_nth_bit(), which is ~70 times faster than bitcounting with
 for_each() loop:
         for_each_set_bit(bit, mask, size)
                 if (n-- == 0)
                         return bit;
 
 Also adds bitmap_weight_and() to let people replace this pattern:
 	tmp = bitmap_alloc(nbits);
 	bitmap_and(tmp, map1, map2, nbits);
 	weight = bitmap_weight(tmp, nbits);
 	bitmap_free(tmp);
 with a single bitmap_weight_and() call.
 
 From me:
 cpumask: repair cpumask_check()
 
 After switching cpumask to use nr_cpu_ids, cpumask_check() started
 generating many false-positive warnings. This series fixes it.
 
 From Valentin Schneider:
 bitmap,cpumask: Add for_each_cpu_andnot() and for_each_cpu_andnot()
 
 Extends the API with one more function and applies it in sched/core.

7f6dcffb44 Preempt RT cleanups: 
Introduce preempt_[dis|enable_nested() and use it to clean up
  various places which have open coded PREEMPT_RT conditionals.
 
  On PREEMPT_RT enabled kernels, spinlocks and rwlocks are neither disabling
  preemption nor interrupts. Though there are a few places which depend on
  the implicit preemption/interrupt disable of those locks, e.g. seqcount
  write sections, per CPU statistics updates etc.
 
  PREEMPT_RT added open coded CONFIG_PREEMPT_RT conditionals to
  disable/enable preemption in the related code parts all over the
  place. That's hard to read and does not really explain why this is
  necessary.
 
  Linus suggested to use helper functions (preempt_disable_nested() and
  preempt_enable_nested()) and use those in the affected places. On !RT
  enabled kernels these functions are NOPs, but contain a lockdep assert to
  validate that preemption is actually disabled to catch call sites which
  do not have preemption disabled.
 
  Clean up the affected code paths in mm, dentry and lib.

493ffd6605 ucounts: Split rlimit and ucount values and max values 
After the ucount rlimit code was merged a bunch of small but
 siginificant bugs were found and fixed.  At the time it was realized
 that part of the problem was that while the ucount rlimits were very
 similar to the oridinary ucounts (in being nested counts with limits)
 the semantics were slightly different and the code would be less error
 prone if there was less sharing.  This is the long awaited cleanup
 that should hopefully keep things more comprehensible and less error
 prone for whoever needs to touch that code next.

Pull ucounts update from Eric Biederman:
 "Split rlimit and ucount values and max values

  After the ucount rlimit code was merged a bunch of small but
  siginificant bugs were found and fixed. At the time it was realized
  that part of the problem was that while the ucount rlimits were very
  similar to the oridinary ucounts (in being nested counts with limits)
  the semantics were slightly different and the code would be less error
  prone if there was less sharing.

  This is the long awaited cleanup that should hopefully keep things
  more comprehensible and less error prone for whoever needs to touch
  that code next"

e572410e47 ptrace: Stop supporting SIGKILL for PTRACE_EVENT_EXIT 
Recently I had a conversation where it was pointed out to me that
 SIGKILL sent to a tracee stropped in PTRACE_EVENT_EXIT is quite
 difficult for a tracer to handle.
 
 Keeping SIGKILL working after the process has been killed is pain
 from an implementation point of view.
 
 So since the debuggers don't want this behavior let's see if we can
 remove this wart for the userspace API
 
 If a regression is detected it should only need to be the last change
 that is the reverted.  The other two are just general cleanups that
 make the last patch simpler.

ef688f8b8c The first batch of KVM patches, mostly covering x86, which I 
am sending out early due to me travelling next week.  There is a
 lone mm patch for which Andrew gave an informal ack at
 https://lore.kernel.org/linux-mm/20220817102500.440c6d0a3fce296fdf91bea6@linux-foundation.org.
 
 I will send the bulk of ARM work, as well as other
 architectures, at the end of next week.
 
 ARM:
 
 * Account stage2 page table allocations in memory stats.
 
 x86:
 
 * Account EPT/NPT arm64 page table allocations in memory stats.
 
 * Tracepoint cleanups/fixes for nested VM-Enter and emulated MSR accesses.
 
 * Drop eVMCS controls filtering for KVM on Hyper-V, all known versions of
   Hyper-V now support eVMCS fields associated with features that are
   enumerated to the guest.
 
 * Use KVM's sanitized VMCS config as the basis for the values of nested VMX
   capabilities MSRs.
 
 * A myriad event/exception fixes and cleanups.  Most notably, pending
   exceptions morph into VM-Exits earlier, as soon as the exception is
   queued, instead of waiting until the next vmentry.  This fixed
   a longstanding issue where the exceptions would incorrecly become
   double-faults instead of triggering a vmexit; the common case of
   page-fault vmexits had a special workaround, but now it's fixed
   for good.
 
 * A handful of fixes for memory leaks in error paths.
 
 * Cleanups for VMREAD trampoline and VMX's VM-Exit assembly flow.
 
 * Never write to memory from non-sleepable kvm_vcpu_check_block()
 
 * Selftests refinements and cleanups.
 
 * Misc typo cleanups.
 
 Generic:
 
 * remove KVM_REQ_UNHALT

The struct sdesc is just a wrapper around shash_desc, with exact same
memory layout. Replace the hashing TFMs with shash_desc as it's what's
passed to the crypto API anyway.

Also remove the crypto_shash pointers as they can be accessed via
shash_desc->tfm (and are actually only used in the setkey calls).

Adapt cifs_{alloc,free}_hash functions to this change.

Pull io_uring updates from Jens Axboe:

 - Add supported for more directly managed task_work running.

   This is beneficial for real world applications that end up issuing
   lots of system calls as part of handling work. Normal task_work will
   always execute as we transition in and out of the kernel, even for
   "unrelated" system calls. It's more efficient to defer the handling
   of io_uring's deferred work until the application wants it to be run,
   generally in batches.

   As part of ongoing work to write an io_uring network backend for
   Thrift, this has been shown to greatly improve performance. (Dylan)

 - Add IOPOLL support for passthrough (Kanchan)

 - Improvements and fixes to the send zero-copy support (Pavel)

 - Partial IO handling fixes (Pavel)

 - CQE ordering fixes around CQ ring overflow (Pavel)

 - Support sendto() for non-zc as well (Pavel)

 - Support sendmsg for zerocopy (Pavel)

bc32a6330f The first two changes that involve files outside of fs/ext4: 
- submit_bh() can never return an error, so change it to return void,
   and remove the unused checks from its callers
 
 - fix I_DIRTY_TIME handling so it will be set even if the inode
   already has I_DIRTY_INODE
 
 Performance:
 
 - Always enable i_version counter (as btrfs and xfs already do).
   Remove some uneeded i_version bumps to avoid unnecessary nfs cache
   invalidations.
 
 - Wake up journal waters in FIFO order, to avoid some journal users
   from not getting a journal handle for an unfairly long time.
 
 - In ext4_write_begin() allocate any necessary buffer heads before
   starting the journal handle.
 
 - Don't try to prefetch the block allocation bitmaps for a read-only
   file system.
 
 Bug Fixes:
 
 - Fix a number of fast commit bugs, including resources leaks and out
   of bound references in various error handling paths and/or if the fast
   commit log is corrupted.
 
 - Avoid stopping the online resize early when expanding a file system
   which is less than 16TiB to a size greater than 16TiB.
 
 - Fix apparent metadata corruption caused by a race with a metadata
   buffer head getting migrated while it was trying to be read.
 
 - Mark the lazy initialization thread freezable to prevent suspend
   failures.
 
 - Other miscellaneous bug fixes.
 
 Cleanups:
 
 - Break up the incredibly long ext4_full_super() function by
   refactoring to move code into more understandable, smaller
   functions.
 
 - Remove the deprecated (and ignored) noacl and nouser_attr mount
   option.
 
 - Factor out some common code in fast commit handling.
 
 - Other miscellaneous cleanups.

Pull btrfs updates from David Sterba:
 "There's a bunch of performance improvements, most notably the FIEMAP
  speedup, the new block group tree to speed up mount on large
  filesystems, more io_uring integration, some sysfs exports and the
  usual fixes and core updates.

  Summary:

  Performance:

   - outstanding FIEMAP speed improvement
      - algorithmic change how extents are enumerated leads to orders of
        magnitude speed boost (uncached and cached)
      - extent sharing check speedup (2.2x uncached, 3x cached)
      - add more cancellation points, allowing to interrupt seeking in
        files with large number of extents
      - more efficient hole and data seeking (4x uncached, 1.3x cached)
      - sample results:
	    256M, 32K extents:   4s ->  29ms  (~150x)
	    512M, 64K extents:  30s ->  59ms  (~550x)
	    1G,  128K extents: 225s -> 120ms (~1800x)

   - improved inode logging, especially for directories (on dbench
     workload throughput +25%, max latency -21%)

   - improved buffered IO, remove redundant extent state tracking,
     lowering memory consumption and avoiding rb tree traversal

   - add sysfs tunable to let qgroup temporarily skip exact accounting
     when deleting snapshot, leading to a speedup but requiring a rescan
     after that, will be used by snapper

   - support io_uring and buffered writes, until now it was just for
     direct IO, with the no-wait semantics implemented in the buffered
     write path it now works and leads to speed improvement in IOPS
     (2x), throughput (2.2x), latency (depends, 2x to 150x)

   - small performance improvements when dropping and searching for
     extent maps as well as when flushing delalloc in COW mode
     (throughput +5MB/s)

  User visible changes:

   - new incompatible feature block-group-tree adding a dedicated tree
     for tracking block groups, this allows a much faster load during
     mount and avoids seeking unlike when it's scattered in the extent
     tree items
      - this reduces mount time for many-terabyte sized filesystems
      - conversion tool will be provided so existing filesystem can also
        be updated in place
      - to reduce test matrix and feature combinations requires no-holes
        and free-space-tree (mkfs defaults since 5.15)

   - improved reporting of super block corruption detected by scrub

   - scrub also tries to repair super block and does not wait until next
     commit

   - discard stats and tunables are exported in sysfs
     (/sys/fs/btrfs/FSID/discard)

   - qgroup status is exported in sysfs
     (/sys/sys/fs/btrfs/FSID/qgroups/)

   - verify that super block was not modified when thawing filesystem

  Fixes:

   - FIEMAP fixes
      - fix extent sharing status, does not depend on the cached status
        where merged
      - flush delalloc so compressed extents are reported correctly

   - fix alignment of VMA for memory mapped files on THP

   - send: fix failures when processing inodes with no links (orphan
     files and directories)

   - fix race between quota enable and quota rescan ioctl

   - handle more corner cases for read-only compat feature verification

   - fix missed extent on fsync after dropping extent maps

  Core:

   - lockdep annotations to validate various transactions states and
     state transitions

   - preliminary support for fs-verity in send

   - more effective memory use in scrub for subpage where sector is
     smaller than page

   - block group caching progress logic has been removed, load is now
     synchronous

   - simplify end IO callbacks and bio handling, use chained bios
     instead of own tracking

   - add no-wait semantics to several functions (tree search, nocow,
     flushing, buffered write

   - cleanups and refactoring

  MM changes:

   - export balance_dirty_pages_ratelimited_flags"

943deb6066 cifs: Replace a couple of one-element arrays with flexible-array members 
One-element arrays are deprecated, and we are replacing them with flexible
array members instead. So, replace one-element arrays with flexible-array
member in structs negotiate_req and extended_response, and refactor the
rest of the code, accordingly.

Also, make use of the DECLARE_FLEX_ARRAY() helper to declare flexible
array member EncryptionKey in union u. This new helper allows for
flexible-array members in unions.

Change pointer notation to proper array notation in a call to memcpy()
where flexible-array member DialectsArray is being used as destination
argument.

Important to mention is that doing a build before/after this patch results
in no binary output differences.

This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy() and help us make progress towards globally
enabling -fstrict-flex-arrays=3 [1].

4659f01e3c smb3: do not log confusing message when server returns no network interfaces 
Some servers can return an empty network interface list so, unless
multichannel is requested, no need to log an error for this, and
when multichannel is requested on mount but no interfaces, log
something less confusing.  For this case change
   parse_server_interfaces: malformed interface info
to
   empty network interface list returned by server localhost

Also do not relog this error every ten minutes (only log on mount, once)

This reverts dbf8e63f48 ("f2fs: remove device type check for direct IO"),
and apply the below first version, since it contributed out-of-order DIO writes.

For zoned devices, f2fs forbids direct IO and forces buffered IO
to serialize write IOs. However, the constraint does not apply to
read IOs.

243a526301 nfsd: rework hashtable handling in nfsd_do_file_acquire 
nfsd_file is RCU-freed, so we need to hold the rcu_read_lock long enough
to get a reference after finding it in the hash. Take the
rcu_read_lock() and call rhashtable_lookup directly.

Switch to using rhashtable_lookup_insert_key as well, and use the usual
retry mechanism if we hit an -EEXIST. Rename the "retry" bool to
open_retry, and eliminiate the insert_err goto target.

8d0d254b15 nfsd: fix nfsd_file_unhash_and_dispose 
nfsd_file_unhash_and_dispose() is called for two reasons:

We're either shutting down and purging the filecache, or we've gotten a
notification about a file delete, so we want to go ahead and unhash it
so that it'll get cleaned up when we close.

We're either walking the hashtable or doing a lookup in it and we
don't take a reference in either case. What we want to do in both cases
is to try and unhash the object and put it on the dispose list if that
was successful. If it's no longer hashed, then we don't want to touch
it, with the assumption being that something else is already cleaning
up the sentinel reference.

Instead of trying to selectively decrement the refcount in this
function, just unhash it, and if that was successful, move it to the
dispose list. Then, the disposal routine will just clean that up as
usual.

Also, just make this a void function, drop the WARN_ON_ONCE, and the
comments about deadlocking since the nature of the purported deadlock
is no longer clear.
