From: Tejun Heo <tj@kernel.org> To: Linus Torvalds <torvalds@linux-foundation.org> Cc: linux-kernel@vger.kernel.org, Li Zefan <lizefan@huawei.com>, cgroups@vger.kernel.org Subject: [GIT PULL] cgroup fixes for v3.17-rc4 Date: Mon, 8 Sep 2014 10:20:25 +0900 [thread overview] Message-ID: <20140908012025.GF5061@mtj.dyndns.org> (raw) Hello, Linus. Up until now, cgroup has allowed any character including '\n' in cgroup names; unfortunately, as '\n' is used as the row delimiter in /proc/$PID/cgroup, '\n' in a cgroup name makes the content of the file ambiguous to parse. This pull request includes Alban's patch to disallow '\n' in cgroup names. While this is a userland visible behavior change, given the craziness of allowing '\n' and its implications, I believe the change is justified. The patch is marked for -stable backport. Two other patches from Li to fix a possible oops when cgroup destruction races against other file operations and one from Vivek to fix a unified hierarchy devel behavior. Thanks.
