locks: make /proc/locks show IS_FILE_PVT locks as type "FLPVT"
In a later patch, we'll be adding a new type of lock that's owned by the struct file instead of the files_struct. Those sorts of locks will be flagged with a new FL_FILE_PVT flag. Report these types of locks as "FLPVT" in /proc/locks to distinguish them from "classic" POSIX locks. Acked-by: J. Bruce Fields <bfields@fieldses.org> Signed-off-by: Jeff Layton <jlayton@redhat.com>
