[PATCH v4 0/3] tracing: signaling large duration and delay

[byungchul . park]

From: Byungchul Park <byungchul.park@xxxxxxx>

Changes since v3
* re-position define macro and undef explicitly
* enhance readablity

Changes since v2
* use inline function instead of macro
* enhance readablity

Changes since v1
* update Document/trace/ftrace.txt
* seperate the implementation as a macro
* apply the implementation to delay printing, too

Hello.

When I analysis the exit_mm() function to find out the reason why the
function spends much time occasionally, this patch was very useful.
I thought this patch cannot be useful only for me, but can be also
useful for anybody who want to be signaled for very large function
execution time, so I decided to submit this patchset.

Nobody who have such a demand? :)

Thanks,
Byungchul.
