From f09b04a03e0239f65bd964a1de758e53cf6349e8 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 21 Dec 2016 14:48:18 +0100 Subject: fsnotify: Remove special handling of mark destruction on group shutdown Currently we queue all marks for destruction on group shutdown and then destroy them from fsnotify_destroy_group() instead from a worker thread which is the usual path. However worker can already be processing some list of marks to destroy so this does not make 100% all marks are really destroyed by the time group is shut down. This isn't a big problem as each mark holds group reference and thus group stays partially alive until all marks are really freed but there's no point in complicating our lives - just wait for the delayed work to be finished instead.
