From 02ba8d211d16f3b385147dd50d7198744e9af59c Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Sun, 23 Mar 2014 15:09:24 +0000 Subject: s390/tape: Use del_timer_sync() 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.
