Subject: [GIT PULL events/urgent] Protect access via task_subsys_state_check()

Hello, Ingo,

This pull request is for an RCU-related bug fix in perf_event_comm().
Without this fix, RCU-lockdep splats and other failures result.

This fix is available in the git repository at:

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git rcu/urgent

It has been subjected to -next testing and was posted to LKML at
https://lkml.org/lkml/2013/4/19/403.

Thanx, Paul

So, I already have this as:

c79aa0d96548 events: Protect access via task_subsys_state_check()

Given the urgency I applied it out of email and will send it to Linus
later today.

Thanks,

Ingo

Thank you, and sorry for the noise!
