Subject: exit,stats: /* obey this comment */
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=51229b495340bd7a02ce3622d1966829b67054ea;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

exit,stats: /* obey this comment */

There is a helpful comment in do_exit() that states we sync the mm's RSS
info before statistics gathering.

The function that does the statistics gathering is called right above that
comment.

Change the code to obey the comment.
