[Test plan]
Build and boot tested, also ran the xfstests for CIFS to ensure basic
functionality was not compromised.
[Where problems could occur]
Although the changes here are somewhat self-contained, the diff is
still sizeable (especially in ffceb7640cbf ("smb: client: do not defer
close open handles to deleted files")), so there is a moderate
regression risk. Issues here would cause hangs and/or faulty behavior
in CIFS filesystems for impacted users.
