lockd: Remove FL_LOCKD flag
Currently lockd identifies its own locks using the FL_LOCKD flag. This doesn't scale well to multiple lock managers--if we did this in nfsv4 too, for example, we'd be left with only one free flag bit. Instead, we just check whether the file manager ops (fl_lmops) set on this lock are our own. The only use for this is in nlm_traverse_locks, which uses it to find locks that need cleaning up when freeing a host or a file. In the long run it might be nice to do reference counting instead of traversing all the locks like this.... Signed-off-by: J.
