[RFC][PATCH 00/12] various perf fixes

Show all headers | View raw

Hi,

I've been hunting perf bugs for the past few weeks. This resulted in this pile
of patches, that mostly seems to work -- I still get an occasional fail so
something is still off.

But I've been sitting on this for far too long, so here goes.

(I've not at all tested perf-cgroup)

The code compiles in between patches, but I've not bothered trying to run/test
any intermediate stage. There's just too many inter-related fail.

Alexander, Stephane, could you guys please have a hard look at this?

Andi, Dmitry, patch 10 should explain the getting stuck in
perf_install_in_context() forever thing you both have observed.
