Possible usage of uninitalized task_ratelimit variable in mm/page-writeback.c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I found a minor issue when compiling kernel today


  CC      mm/page-writeback.o
mm/page-writeback.c: In function ‘balance_dirty_pages_ratelimited_nr’:
include/trace/events/writeback.h:281:1: warning: ‘task_ratelimit’ may be used uninitialized in this function [-Wuninitialized]
mm/page-writeback.c:1018:16: note: ‘task_ratelimit’ 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
