From 386cb7cdeeef97e0bf082a8d6bbfc07a2ccce07b Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Thu, 16 Jul 2015 21:16:31 -0400 Subject: [PATCH] dm cache: do not wake_worker() in free_migration() All methods that queue work call wake_worker() as you'd expect. E.g. cell_defer, defer_bio, quiesce_migration (which is called by writeback, promote, demote_then_promote, invalidate, discard, etc).
