* 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.
