The patch titled

This patch was dropped because an updated version will be merged
------------------------------------------------------
From: Jan Kara <jack@xxxxxxx>
Subject: fsnotify: remove destroy_list from fsnotify_mark
destroy_list is used to track marks which still need waiting for srcu
period end before they can be freed. However by the time mark is added to
destroy_list it isn't in group's list of marks anymore and thus we can
reuse fsnotify_mark->g_list for queueing into destroy_list. This saves
two pointers for each fsnotify_mark.
