[GIT PULL] vfs fixes

[Christian Brauner]

Hey Linus,

/* Summary */
This contains a few small fixes for this merge window:

* Undo the hiding of silly-rename files in afs. If they're hidden they
  can't be deleted by rm manually anymore causing regressions.
* Avoid caching the preferred address for an afs server to avoid
  accidently overriding an explicitly specified preferred server address.
* Fix bad stat() and rmdir() interaction in afs.
* Take a passive reference on the superblock when opening a block device
  so the holder is available to concurrent callers from the block layer.
* Clear private data pointer in fscache_begin_operation() to avoid it
  being falsely treated as valid.

/* Testing */
clang: Debian clang version 16.0.6 (19)
gcc: (Debian 13.2.0-7) 13.2.0

All patches are based on mainline and have been sitting in linux-next.
No build failures or warnings were observed.
