Subject: [patch 01/16] s390: tape: Use del_timer_sync()
Date: Sun, 23 Mar 2014 15:09:24 -0000 [thread overview]
Message-ID: <20140323150752.607059123@linutronix.de> (raw)
In-Reply-To: 20140323150557.288925975@linutronix.de
[-- Attachment #1: s390-tape-use-del-timer-sync.patch --]
[-- Type: text/plain, Size: 846 bytes --]
del_timer() does not wait for a possible running callback to
complete. So the call side might free request and the associated
objects while on another cpu the timer handler runs.
