Subject: Possible usage of uninitalized task_ratelimit variable in mm/page-writeback.c
Date: Mon, 7 Nov 2011 09:18:24 +0100 [thread overview]
Message-ID: <20111107081824.GA18221@smp.if.uj.edu.pl> (raw)
Hi,
I found a minor issue when compiling kernel today
CC mm/page-writeback.o
mm/page-writeback.c: In function a??balance_dirty_pages_ratelimited_nra??:
include/trace/events/writeback.h:281:1: warning: a??task_ratelimita?? may be used uninitialized in this function [-Wuninitialized]
mm/page-writeback.c:1018:16: note: a??task_ratelimita?? was declared here
Indeed in balance_dirty_pages a task_ratelimit may be not initialized
(initialization skiped by goto pause;), and then used when calling
tracing hook.
Regards,
Witek
