fcf50d161c btrfs: convert begin_page_folio() to take a folio instead 
This already uses a folio internally, change it to take a folio as an
argument instead.

645006d87c btrfs: convert end_page_read() to take a folio 
We have this helper function to set the page range uptodate once we're
done reading it, as well as run fsverity against it.  Half of these
functions already take a folio, just rename this to end_folio_read and
then rework it to take a folio instead, and update everything
accordingly.

45714ff75c btrfs: print message on device opening error during mount 
[ENHANCEMENT]
When mounting a btrfs filesystem, the filesystem opens the block device,
and if this fails, there is no message about it. Print a message about
it to help debugging.

[TEST]
I have a btrfs filesystem on three block devices, one of which is
write-protected, so regular mounts fail, but there is no message in
dmesg.

  /dev/vdb normal
  /dev/vdc write protected
  /dev/vdd normal

  Before patch:
  $ sudo mount /dev/vdb /mnt/
  mount: mount(2) failed: no such file or directory
  $ sudo dmesg # Show only messages about missing block devices
  ....
  [ 352.947196] BTRFS error (device vdb): devid 2 uuid 4ee2c625-a3b2-4fe0-b411-756b23e08533 missing
  ....

  After patch:
  $ sudo mount /dev/vdb /mnt/
  mount: mount(2) failed: no such file or directory
  $ sudo dmesg # Show bdev_file_open_by_path failed.
  ....
  [ 352.944328] BTRFS error: failed to open device for path /dev/vdc with flags 0x3: -13

UUID tree rescan and creation, it's not suitable for volumes.[ch].

ab094670fa btrfs: reduce size and overhead of extent_map_block_end() 
At extent_map_block_end() we are calling the inline functions
extent_map_block_start() and extent_map_block_len() multiple times, which
results in expanding their code multiple times, increasing the compiled
code size and repeating the computations those functions do.

Improve this by caching their results in local variables.

The size of the module before this change:

   $ size fs/btrfs/btrfs.ko
      text	   data	    bss	    dec	    hex	filename
   1755770	 163800	  16920	1936490	 1d8c6a	fs/btrfs/btrfs.ko

And after this change:

   $ size fs/btrfs/btrfs.ko
      text	   data	    bss	    dec	    hex	filename
   1755656	 163800	  16920	1936376	 1d8bf8	fs/btrfs/btrfs.ko

7fa5230b46 btrfs: update stripe_extent delete loop assumptions 
btrfs_delete_raid_extent() was written under the assumption, that it's
call-chain always passes a start, length tuple that matches a single
extent. But btrfs_delete_raid_extent() is called by
do_free_extent_accounting() which in turn is called by
__btrfs_free_extent().

But this call-chain passes in a start address and a length that can
possibly match multiple on-disk extents.

To make this possible, we have to adjust the start and length of each
btree node lookup, to not delete beyond the requested range.

8c4cba2adb btrfs: update stripe extents for existing logical addresses 
Update a stripe extent in case of an already existing logical address,
but with different physical addresses and/or device id instead of
bailing out with EEXIST.

This can happen i.e. in case of a device replace operation, where data
extents get rewritten to a new disk.

d1f2d51b71 A pile of Qualcomm clk driver fixes with two main themes: the alpha PLL 
driver and shared RCGs, and one fix for the Starfive JH7110 SoC.
 
  - The Alpha PLL clk_ops had multiple problems around setting rates.
    There are a handful of patches here that fix masks and skip enabling
    the clk from set_rate() when the PLL is disabled. The PLLs are
    crucial to operation of the system as almost all frequencies in the
    system are derived from them.
 
  - Parking shared RCGs at a slow always on clk at registration time
    breaks stuff. USB host mode can't handle such a slow frequency and
    the serial console gets all garbled when the UART clk is handed over
    to the kernel. There's a few patches that don't use the shared
    clk_ops for the UART clks and another one to skip parking the USB clk
    at registration time.
 
  - The Starfive PLL driver used for the CPU was busted causing cpufreq
    to fail because the clk didn't change to a safe parent during
    set_rate(). The fix is to register a notifier and switch to a safe
    parent so the PLL can change rate in a glitch free manner.

9d4c304001 KVM: x86: don't fall through case statements without annotations 
clang warns on this because it has an unannotated fall-through between
cases:

   arch/x86/kvm/x86.c:4819:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]

and while we could annotate it as a fallthrough, the proper fix is to
just add the break for this case, instead of falling through to the
default case and the break there.

gcc also has that warning, but it looks like gcc only warns for the
cases where they fall through to "real code", rather than to just a
break.  Odd.

703896be30 sound fixes for 6.11-rc7 
Hopefully the last PR for 6.11, at least for this level of amount.
 
 In addition to the usual HD-audio quirks, there are more changes in
 ASoC, but all look small and device-specific fixes, and nothing stands
 out.  The only slightly big change is sunxi I2S fix, which looks quite
 safe to apply, too.

8654fa5ca3 pwm: Fix an off-by-one in the stm32 driver 
Hardware engineers tend to start counting at 1 while the software guys
 usually start with 0. This isn't so nice because that results in drivers
 where pwm device #2 needs to use the hardware registers with index 3.
 
 With the commits
 
 	796b942f65 ("mfd: stm32-timers: Add some register definitions with a parameter")
 	7cea05ae1d ("pwm-stm32: Make use of parametrised register definitions")
 
 (merged for v6.11-rc1) I tried to improve the situation and make this
 counting mismatch more explicit and transparent. However in one instance
 I failed to add the needed +1.
 
 This was noticed by Fabrice Gasnier (however in a way that made me
 hesitate to add a "Reported-by:" tag, see
 https://lore.kernel.org/linux-pwm/3515a8f3-436e-4d14-9bac-dfe6aa869819@foss.st.com),
 thanks to him for catching the issue.
 
 A small patch fixing that mismatch is the only change included here.

4e32c25b58 libfs: fix get_stashed_dentry() 
get_stashed_dentry() tries to optimistically retrieve a stashed dentry
from a provided location.  It needs to ensure to hold rcu lock before it
dereference the stashed location to prevent UAF issues.  Use
rcu_dereference() instead of READ_ONCE() it's effectively equivalent
with some lockdep bells and whistles and it communicates clearly that
this expects rcu protection.

SOF which ensures that a struct layout doesn't vary depending on the
architecture of the host.

Linus Torvalds
e4b42053b7 Tracing fixes for 6.11: 
- Fix adding a new fgraph callback after function graph tracing has
   already started.
 
   If the new caller does not initialize its hash before registering the
   fgraph_ops, it can cause a NULL pointer dereference. Fix this by adding
   a new parameter to ftrace_graph_enable_direct() passing in the newly
   added gops directly and not rely on using the fgraph_array[], as entries
   in the fgraph_array[] must be initialized. Assign the new gops to the
   fgraph_array[] after it goes through ftrace_startup_subops() as that
   will properly initialize the gops->ops and initialize its hashes.
 
 - Fix a memory leak in fgraph storage memory test.
 
   If the "multiple fgraph storage on a function" boot up selftest
   fails in the registering of the function graph tracer, it will
   not free the memory it allocated for the filter. Break the loop
   up into two where it allocates the filters first and then registers
   the functions where any errors will do the appropriate clean ups.
 
 - Only clear the timerlat timers if it has an associated kthread.
 
   In the rtla tool that uses timerlat, if it was killed just as it
   was shutting down, the signals can free the kthread and the timer.
   But the closing of the timerlat files could cause the hrtimer_cancel()
   to be called on the already freed timer. As the kthread variable is
   is set to NULL when the kthreads are stopped and the timers are freed
   it can be used to know not to call hrtimer_cancel() on the timer if
   the kthread variable is NULL.
 
 - Use a cpumask to keep track of osnoise/timerlat kthreads
 
   The timerlat tracer can use user space threads for its analysis.
   With the killing of the rtla tool, the kernel can get confused
   between if it is using a user space thread to analyze or one of its
   own kernel threads. When this confusion happens, kthread_stop()
   can be called on a user space thread and bad things happen.
   As the kernel threads are per-cpu, a bitmask can be used to know
   when a kernel thread is used or when a user space thread is used.
 
 - Add missing interface_lock to osnoise/timerlat stop_kthread()
 
   The stop_kthread() function in osnoise/timerlat clears the
   osnoise kthread variable, and if it was a user space thread does
   a put_task on it. But this can race with the closing of the timerlat
   files that also does a put_task on the kthread, and if the race happens
   the task will have put_task called on it twice and oops.
 
 - Add cond_resched() to the tracing_iter_reset() loop.
 
   The latency tracers keep writing to the ring buffer without resetting
   when it issues a new "start" event (like interrupts being disabled).
   When reading the buffer with an iterator, the tracing_iter_reset()
   sets its pointer to that start event by walking through all the events
   in the buffer until it gets to the time stamp of the start event.

Pull tracing fixes from Steven Rostedt:

 - Fix adding a new fgraph callback after function graph tracing has
   already started.

   If the new caller does not initialize its hash before registering the
   fgraph_ops, it can cause a NULL pointer dereference. Fix this by
   adding a new parameter to ftrace_graph_enable_direct() passing in the
   newly added gops directly and not rely on using the fgraph_array[],
   as entries in the fgraph_array[] must be initialized.

   Assign the new gops to the fgraph_array[] after it goes through
   ftrace_startup_subops() as that will properly initialize the
   gops->ops and initialize its hashes.

 - Fix a memory leak in fgraph storage memory test.

   If the "multiple fgraph storage on a function" boot up selftest fails
   in the registering of the function graph tracer, it will not free the
   memory it allocated for the filter. Break the loop up into two where
   it allocates the filters first and then registers the functions where
   any errors will do the appropriate clean ups.

 - Only clear the timerlat timers if it has an associated kthread.

   In the rtla tool that uses timerlat, if it was killed just as it was
   shutting down, the signals can free the kthread and the timer. But
   the closing of the timerlat files could cause the hrtimer_cancel() to
   be called on the already freed timer. As the kthread variable is is
   set to NULL when the kthreads are stopped and the timers are freed it
   can be used to know not to call hrtimer_cancel() on the timer if the
   kthread variable is NULL.

 - Use a cpumask to keep track of osnoise/timerlat kthreads

   The timerlat tracer can use user space threads for its analysis. With
   the killing of the rtla tool, the kernel can get confused between if
   it is using a user space thread to analyze or one of its own kernel
   threads. When this confusion happens, kthread_stop() can be called on
   a user space thread and bad things happen. As the kernel threads are
   per-cpu, a bitmask can be used to know when a kernel thread is used
   or when a user space thread is used.

 - Add missing interface_lock to osnoise/timerlat stop_kthread()

   The stop_kthread() function in osnoise/timerlat clears the osnoise
   kthread variable, and if it was a user space thread does a put_task
   on it. But this can race with the closing of the timerlat files that
   also does a put_task on the kthread, and if the race happens the task
   will have put_task called on it twice and oops.

 - Add cond_resched() to the tracing_iter_reset() loop.

   The latency tracers keep writing to the ring buffer without resetting
   when it issues a new "start" event (like interrupts being disabled).
   When reading the buffer with an iterator, the tracing_iter_reset()
   sets its pointer to that start event by walking through all the
   events in the buffer until it gets to the time stamp of the start
   event. In the case of a very large buffer, the loop that looks for
   the start event has been reported taking a very long time with a non
   preempt kernel that it can trigger a soft lock up warning. Add a
   cond_resched() into that loop to make sure that doesn't happen.

 - Use list_del_rcu() for eventfs ei->list variable

   It was reported that running loops of creating and deleting kprobe
   events could cause a crash due to the eventfs list iteration hitting
   a LIST_POISON variable. This is because the list is protected by SRCU
   but when an item is deleted from the list, it was using list_del()
   which poisons the "next" pointer. This is what list_del_rcu() was to
   prevent.

031ae72825 ila: call nf_unregister_net_hooks() sooner 
syzbot found an use-after-free Read in ila_nf_input [1]

Issue here is that ila_xlat_exit_net() frees the rhashtable,
then call nf_unregister_net_hooks().

It should be done in the reverse way, with a synchronize_rcu().

This is a good match for a pre_exit() method.

Parsing Generic Netlink notification messages performs lookup for op in
the message. The message was not yet decoded, and is not yet considered
GenlMsg, thus msg.cmd() returns Generic Netlink family id (19) instead of
proper notification command id (i.e.: DPLL_CMD_PIN_CHANGE_NTF=13).

Allow the op to be obtained within NetlinkProtocol.decode(..) itself if the
op was not passed to the decode function, thus allow parsing of Generic
Netlink notifications without causing the failure.
