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

Added to the queue for 3.2, thanks.

Life would be so much easier if we could look at the source code.
