From: Eric Paris Date: Fri, 18 Dec 2009 02:24:33 +0000 (-0500) Subject: fanotify: allow ignored_masks to survive modify X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c9778a98e7440fb73e0d27b8155a688663a0d493;p=linux-beck.git fanotify: allow ignored_masks to survive modify Some users may want to truely ignore an inode even if it has been modified. Say you are wanting a mount which contains a log file and you really don't want any notification about that file. This patch allows the listener to do that.
