From 418df63c2d94f238ac7e1d1d53be35dd6b7a7252 Mon Sep 17 00:00:00 2001 From: Jonathan Corbet Date: Wed, 22 Apr 2009 12:01:49 +0100 Subject: Delete slow-work timers properly Slow-work appears to delete its timer as soon as the first user unregisters, even though other users could be active. At the same time, it never seems to delete slow_work_oom_timer. Arrange for both to happen in the shutdown path.
