From 7117bf3dfb10b534a017260d9fc643bc1d0afd2a Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Mon, 20 Mar 2006 13:44:26 -0500 Subject: 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.
