workqueue: Fix type of cpu in trace event
The trace event "workqueue_queue_work" use unsigned int type for req_cpu, cpu. This casue confusing cpu number like below log. $ cat /sys/kernel/debug/tracing/trace cat-317 [001] ...: workqueue_queue_work: ... req_cpu=8192 cpu=4294967295 So, change unsigned type to signed type in the trace event. After applying this patch, cpu number will be printed as -1 instead of 4294967295 as folllows. $ cat /sys/kernel/debug/tracing/trace cat-1338 [002] ...: workqueue_queue_work: ... req_cpu=8192 cpu=-1 Cc: Baik Song An <bsahn@etri.re.kr> Cc: Hong Yeon Kim <kimhy@etri.re.kr> Cc: Taeung Song <taeung@reallinux.co.kr> Cc: linuxgeek@linuxgeek.io Signed-off-by: Wonhyuk Yang <vvghjk1234@gmail.com> Signed-off-by: Tejun Heo <tj@kernel.org>
