From 7b1293234084ddb6469c4e9a5ef818f399b5786b Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 21 Dec 2016 18:32:48 +0100 Subject: fsnotify: Add group pointer in fsnotify_init_mark() Currently we initialize mark->group only in fsnotify_add_mark_lock(). However we will need to access fsnotify_ops of corresponding group from fsnotify_put_mark() so we need mark->group initialized earlier. Do that in fsnotify_init_mark() which has a consequence that once fsnotify_init_mark() is called on a mark, the mark has to be destroyed by fsnotify_put_mark().
