    Partially revert "locks: fix file locking on overlayfs" · de2a4a50

    This partially reverts commit c568d683.
    
    Overlayfs files will now automatically get the correct locks, no need to
    hack overlay support in VFS.
    
    It is a partial revert, because it leaves the locks_inode() calls in place
    and defines locks_inode() to file_inode().  We could revert those as well,
    but it would be unnecessary code churn and it makes sense to document that
    we are getting the inode for locking purposes.
    
    Don't revert MS_NOREMOTELOCK yet since that has been part of the userspace
    API for some time (though not in a useful way).  Will try to remove
    internal flags later when the dust around the new mount API settles.
