Subject: [RFC][PATCH 00/12] various perf fixes
Date: Mon, 11 Jan 2016 17:24:58 +0100 [thread overview]
Message-ID: <20160111162458.427203780@infradead.org> (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.
