[ Upstream commit 4fc3a433c13944ee5766ec5b9bf6f1eb4d29b880 ]
Use atomic_t for cifs_sb_info::mnt_cifs_flags as it's currently
accessed locklessly and may be changed concurrently in mount/remount
and reconnect paths.

Adapt the atomic conversion to the 6.6 SMB client. Keep the existing
CIFS_SB/CIFS_FILE_SB interfaces, cifs_remap implementation, shutdown
helper, and smb3_update_mnt_flags signature. Omit the unrelated generic
superblock accessors and changes to newer symlink and I/O code.
Provide cifs_sb_flags as a single-evaluation macro, with the same unsigned
atomic read as upstream, without adding functions. Convert every existing
flag reader and use atomic_or/atomic_andnot for flag updates, including
the legacy reset_cifs_unix_caps path. Keeping bitwise updates in the
mount/remount paths also preserves concurrent changes to other flag bits.
Retain the cifs_getattr sbflags snapshot so cf4d35896621 applies unchanged.
The POSIX ownership condition itself remains for that target commit.
[ sashal: Reduced backport -- upstream 4fc3a433c1394 touches 27 file(s), this
backport carries 23. Not backported here:
fs/smb/client/cifs_unicode.h
fs/smb/client/fs_context.h
fs/smb/client/reparse.c
fs/smb/client/smb2file.c
This note is generated from the file lists only; see the resolution record
for the reasoning. ]
