Pull smb server update from Steve French:
 "After two years, many fixes and much testing, ksmbd is no longer
  experimental"

* tag '6.6-rc-ksmbd' of git://git.samba.org/ksmbd:

Recently we moved most cleanup from ntfs_put_super() into
ntfs3_kill_sb() as part of a bigger cleanup.  This accidently also moved
dropping inode references stashed in ntfs3's sb->s_fs_info from
@sb->put_super() to @sb->kill_sb().  But generic_shutdown_super()
verifies that there are no busy inodes past sb->put_super().  Fix this
and disentangle dropping inode references from freeing @sb->s_fs_info.

Mateusz reports that glibc turns 'fstat()' calls into 'fstatat()', and
that seems to have been going on for quite a long time due to glibc
having tried to simplify its stat logic into just one point.

This turns out to cause completely unnecessary overhead, where we then
go off and allocate the kernel side pathname, and actually look up the
empty path.  Sure, our path lookup is quite optimized, but it still
causes a fair bit of allocation overhead and a couple of completely
unnecessary rounds of lockref accesses etc.

This is all hopefully getting fixed in user space, and there is a patch
floating around for just having glibc use the native fstat() system
call.  But even with the current situation we can at least improve on
things by catching the situation and short-circuiting it.

Note that this is still measurably slower than just a plain 'fstat()',
since just checking that the filename is actually empty is somewhat
expensive due to inevitable user space access overhead from the kernel
(ie verifying pointers, and SMAP on x86).  But it's still quite a bit
faster than actually looking up the path for real.

To quote numers from Mateusz:
 "Sapphire Rapids, will-it-scale, ops/s

  stock fstat	5088199
  patched fstat	7625244	(+49%)
  real fstat	8540383	(+67% / +12%)"

where that 'stock fstat' is the glibc translation of fstat into
fstatat() with an empty path, the 'patched fstat' is with this short
circuiting of the path lookup, and the 'real fstat' is the actual native
fstat() system call with none of this overhead.

In debugging a recent performance problem with statfs, it would have
been helpful to be able to trace the smb3 query fs info request
more narrowly.  Add a trace point "smb3_qfs_done"

Which displays:

 stat-68950   [008] .....  1472.360598: smb3_qfs_done: xid=14 sid=0xaa9765e4 tid=0x95a76f54 unc_name=\\localhost\test rc=0

Pull ceph updates from Ilya Dryomov:
 "Mixed with some fixes and cleanups, this brings in reasonably complete
  fscrypt support to CephFS! The list of things which don't work with
  encryption should be fairly short, mostly around the edges: fallocate
  (not supported well in CephFS to begin with), copy_file_range
  (requires re-encryption), non-default striping patterns.

  This was a multi-year effort principally by Jeff Layton with
  assistance from Xiubo Li, Luís Henriques and others, including several
  dependant changes in the MDS, netfs helper library and fscrypt
  framework itself"

Pull gfs2 updates from Andreas Gruenbacher:

 - Fix a glock state (non-)transition bug when a dlm request times out
   and is canceled, and we have locking requests that can now be granted
   immediately

 - Various fixes and cleanups in how the logd and quotad daemons are
   woken up and terminated

 - Fix several bugs in the quota data reference counting and shrinking.
   Free quota data objects synchronously in put_super() instead of
   letting call_rcu() run wild

 - Make sure not to deallocate quota data during a withdraw; rather,
   defer quota data deallocation to put_super(). Withdraws can happen in
   contexts in which callers on the stack are holding quota data
   references

 - Many minor quota fixes and cleanups by Bob

 - Update the the mailing list address for gfs2 and dlm. (It's the same
   list for both and we are moving it to gfs2@lists.linux.dev)

 - Various other minor cleanups
