Subject[GIT PULL] cgroup fixes for v3.17-rc4
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.
