Merge tag 'vfs-6.19-rc1.guards' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull superblock lock guard updates from Christian Brauner:
 "This starts the work of introducing guards for superblock related
  locks.

  Introduce super_write_guard for scoped superblock write protection.

  This provides a guard-based alternative to the manual sb_start_write()
  and sb_end_write() pattern, allowing the compiler to automatically
  handle the cleanup"
