From d8153d4d8b7b6141770e1416c4a338161205ed1b Mon Sep 17 00:00:00 2001 From: Lino Sanfilippo Date: Tue, 14 Jun 2011 17:29:45 +0200 Subject: inotify, fanotify: replace fsnotify_put_group() with fsnotify_destroy_group() Currently in fsnotify_put_group() the ref count of a group is decremented and if it becomes 0 fsnotify_destroy_group() is called. Since a groups ref count is only at group creation set to 1 and never increased after that a call to fsnotify_put_group() always results in a call to fsnotify_destroy_group(). With this patch fsnotify_destroy_group() is called directly.
