Subject: Query: Notifier support for callback profiling
Date: Fri, 19 May 2017 19:01:34 +0530 [thread overview]
Message-ID: <8738660c-a644-6f9f-4da4-1d3349c3f9ea@codeaurora.org> (raw)
Hi ,
Can we profile driver specific notifier callback from Linux notifier.
Sometimes we need to debug which callback is taking more time or where
it is stuck.
If kernel/notifier.c provide generic mechanism to profile callbacks that
will
save profiling individual callbacks.
