Merge tag 'vfs-6.14-rc2.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs fixes from Christian Brauner:

 - Fix fsnotify FMODE_NONOTIFY* handling.

   This also disables fsnotify on all pseudo files by default apart from
   very select exceptions. This carries a regression risk so we need to
   watch out and adapt accordingly. However, it is overall a significant
   improvement over the current status quo where every rando file can
   get fsnotify enabled.

 - Cleanup and simplify lockref_init() after recent lockref changes.

 - Fix vboxfs build with gcc-15.

 - Add an assert into inode_set_cached_link() to catch corrupt links.

 - Allow users to also use an empty string check to detect whether a
   given mount option string was empty or not.

 - Fix how security options were appended to statmount()'s ->mnt_opt
   field.

 - Fix statmount() selftests to always check the returned mask.

 - Fix uninitialized value in vfs_statx_path().

 - Fix pidfs_ioctl() sanity checks to guard against ioctl() overloading
   and preserve extensibility.
