| |
3.16.37-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Oliver Neukum <oneukum@suse.com>
commit ed596a4a88bd161f868ccba078557ee7ede8a6ef upstream.
Flushing a work that reschedules itself is not a sensible operation. It needs to be killed. Failure to do so leads to a kernel panic in the timer code.
