Subject: Add to stable: tracing: change CPU ring buffer state from tracing_cpumask
Date: Mon, 02 Jul 2012 11:43:29 -0400	[thread overview]
Message-ID: <1341243809.6578.5.camel@gandalf.stny.rr.com> (raw)

Hi Greg,

Thomas pointed out that the buffering for tracing (other than function
tracer - and other "tracers") is not affected by the tracing_cpumask.
This goes back to 3.0 (and probably before that).

It's fixed with this commit: 71babb2705e2203a64c27ede13ae3508a0d2c16c
"tracing: change CPU ring buffer state from tracing_cpumask"

Which looks to have made it into 3.5-rc1. Can you apply this to all the
stable trees from 3.0 and beyond.

Thanks,

-- Steve
