fh_match() is costly, especially when filehandles are large (as is
the case for NFSv4). It needs to be used sparingly when searching
data structures. Unfortunately, with common workloads, I see
multiple thousands of objects stored in file_hashtbl[], which has
just 256 buckets, making its bucket hash chains quite lengthy.
Walking long hash chains with the state_lock held blocks other
activity that needs that lock. Sizable hash chains are a common
occurrance once the server has handed out some delegations, for
example -- IIUC, each delegated file is held open on the server by
an nfs4_file object.
To help mitigate the cost of searching with fh_match(), replace the
nfs4_file hash table with an rhashtable, which can dynamically
resize its bucket array to minimize hash chain length.
The result of this modification is an improvement in the latency of
NFSv4 operations, and the reduction of nfsd CPU utilization due to
eliminating the cost of multiple calls to fh_match() and reducing
the CPU cache misses incurred while walking long hash chains in the
nfs4_file hash table.

Remove the call to find_file_locked() in insert_nfs4_file(). Tracing
shows that over 99% of these calls return NULL. Thus it is not worth
the expense of the extra bucket list traversal. insert_file() already
deals correctly with the case where the item is already in the hash
bucket.
Since nfsd4_file_hash_insert() is now just a wrapper around
insert_file(), move the meat of insert_file() into
nfsd4_file_hash_insert() and get rid of it.

Refactor to relocate hash deletion operation to a helper function
that is close to most other nfs4_file data structure operations.
The "noinline" annotation will become useful in a moment when the
hlist_del_rcu() is replaced with a more complex rhash remove
operation. It also guarantees that hash remove operations can be
traced with "-p function -l remove_nfs4_file_locked".
This also simplifies the organization of forward declarations: the
to-be-added rhashtable and its param structure will be defined
/after/ put_nfs4_file().

NFSv4 operations manage the lifetime of nfsd_file items they use by
means of NFSv4 OPEN and CLOSE. Hence there's no need for them to be
garbage collected.
Introduce a mechanism to enable garbage collection for nfsd_file
items used only by NFSv2/3 callers.
Note that the change in nfsd_file_put() ensures that both CLOSE and
DELEGRETURN will actually close out and free an nfsd_file on last
reference of a non-garbage-collected file.

This reverts commit 5e138c4a75.
That commit attempted to make files available to other users as soon
as all NFSv4 clients were done with them, rather than waiting until
the filecache LRU had garbage collected them.
It gets the reference counting wrong, for one thing.
But it also misses that DELEGRETURN should release a file in the
same fashion. In fact, any nfsd_file_put() on an file held open
by an NFSv4 client needs potentially to release the file
immediately...
Clear the way for implementing that idea.

rpc.nfsd stopped supporting NFSv2 a year ago. Take the next logical
step toward deprecating it and allow NFSv2 support to be compiled out.
Add a new CONFIG_NFSD_V2 option that can be turned off and rework the
CONFIG_NFSD_V?_ACL option dependencies. Add a description that
discourages enabling it.
Also, change the description of CONFIG_NFSD to state that the always-on
version is now 3 instead of 2.
Finally, add an #ifdef around "case 2:" in __write_versions. When NFSv2
is disabled at compile time, this should make the kernel ignore attempts
to disable it at runtime, but still error out when trying to enable it.

"Two more fixes to the perf sigtrap handling:
- output the address in the sample only when it has been requested
- handle the case where user-only events can hit in kernel and thus
upset the sigtrap sanity checking"
* tag 'perf_urgent_for_v6.1_rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
perf: Consider OS filter fail
perf: Fixup SIGTRAP and sample_flags interaction
* Fixes for Xen emulation. While nobody should be enabling it in
the kernel (the only public users of the feature are the selftests),
the bug effectively allows userspace to read arbitrary memory.
* Correctness fixes for nested hypervisors that do not intercept INIT
or SHUTDOWN on AMD; the subsequent CPU reset can cause a use-after-free
when it disables virtualization extensions. While downgrading the panic
to a WARN is quite easy, the full fix is a bit more laborious; there
are also tests. This is the bulk of the pull request.

make_mmu_pages_available().

* Obey changes to the kvm.halt_poll_ns module parameter in VMs
not using KVM_CAP_HALT_POLL, restoring behavior from before

This is more changes than I'd like this late although the diffstat is

things time to soak in -next but should probably have tagged and sent an
additional pull request earlier.
There's some relatively large fixes to the twl6030 driver to fix issues
with the TWL6032 variant which resulted from some work on the core
TWL6030 driver, a couple of fixes for error handling paths (mostly in
the core), and a nice stability fix for the sgl51000 driver that's been

- Revert a recent schedutil cpufreq governor change that introduced
a performace regression on Pixel 6 (Sam Wu).
- Fix amd-pstate driver initialization after running the kernel via
kexec (Wyes Karny).
- Turn amd-pstate into a built-in driver which allows it to take
precedence over acpi-cpufreq by default on supported systems and
amend it with a mechanism to disable this behavior (Perry Yuan).
- Update amd-pstate documentation in accordance with the other changes
made to it (Perry Yuan).

Merge tag 'pm-6.1-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki:
"These revert a recent change in the schedutil cpufreq governor that
had not been expected to make any functional difference, but turned
out to introduce a performance regression, fix an initialization issue
in the amd-pstate driver and make it actually replace the venerable
ACPI cpufreq driver on the supported systems by default.
Specifics:
- Revert a recent schedutil cpufreq governor change that introduced a
performace regression on Pixel 6 (Sam Wu)
- Fix amd-pstate driver initialization after running the kernel via
kexec (Wyes Karny)
- Turn amd-pstate into a built-in driver which allows it to take
precedence over acpi-cpufreq by default on supported systems and

There have been a lot of hotfixes this cycle, and this is quite a large
batch given how far we are into the -rc cycle. Presumably a reflection of
the unusually large amount of MM material which went into 6.1-rc1.
