From a092ee20fd33d2df0990dcbf2235afc181612818 Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Thu, 11 Jun 2009 11:09:48 -0400 Subject: [PATCH] fsnotify: allow groups to set freeing_mark to null Most fsnotify listeners (all but inotify) do not care about marks being freed. Allow groups to set freeing_mark to null and do not call any function if it is set that way.
