The patch titled
cgroups: annotate two variables with __read_mostly
has been removed from the -mm tree. Its filename was
cgroup-anotate-two-variables-with-__read_mostly.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: cgroups: annotate two variables with __read_mostly
From: Li Zefan <lizf@xxxxxxxxxxxxxx>
- need_forkexit_callback will be read only after system boot.
- use_task_css_set_links will be read only after it's set.
And these 2 variables are checked when a new process is forked.
