Merge tag 'v6.6-vfs.super.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull superblock fixes from Christian Brauner:
 "Two follow-up fixes for the super work this cycle:

   - Move a misplaced lockep assertion before we potentially free the
     object containing the lock.

   - Ensure that filesystems which match superblocks in sget{_fc}()
     based on sb->s_fs_info are guaranteed to see a valid sb->s_fs_info
     as long as a superblock still appears on the filesystem type's
     superblock list.

     What we want as a proper solution for next cycle is to split
     sb->free_sb() out of sb->kill_sb() so that we can simply call
     kill_super_notify() after sb->kill_sb() but before sb->free_sb().

     Currently, this is lumped together in sb->kill_sb()"
