From 80bd7181b036c7b4118eb19cfff3b555889596e6 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Wed, 30 Jan 2013 09:26:17 +0000 Subject: [PATCH] block: check for timeout function in blk_rq_timed_out() rq_timed_out_fn might have been unset while the request was in flight, so we need to check for it in blk_rq_timed_out().
