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.
