Given recent breakage, has the patchset been run through any tests on 
older kernels that do not support sample_id_all? e.g., 2.6.34 (WRL4). 
What about tests with the other perf commands -- script to dump events, 
trace on a file with with multiple processes -- to verify no impact on 
comm output, especially multithreaded processes with named threads. I 
can certainly do those tests in time, but can't guarantee a timeframe 
and want to make sure it gets done before merging.

Thanks,
David
