From c908370fc1ac27fd7e1fc0f34c693047b26564ce Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Thu, 17 Dec 2009 21:24:33 -0500 Subject: fsnotify: allow ignored_mask to survive modification Some inodes a group may want to never hear about a set of events even if the inode is modified. We add a new mark flag which indicates that these marks should not have their ignored_mask cleared on modification.
