Subject: perf cgroup per-task attaching
Date: Tue, 31 May 2011 16:03:59 +0200 [thread overview]
Message-ID: <20110531140359.GA13134@aftab> (raw)
Just FYI:
I'm getting
kernel/events/core.c:7445: warning: initialization from incompatible pointer type
when building -rc1 with CONFIG_CGROUP_PERF enabled. AFAICT, this is
due to the fact that f780bdb7c1c73009cb57adcf99ef50027d80bf3c dropped
the threadgroup arg from cgroup_subsys->attach in favour of per-thread
callbacks.
perf_cgroup_attach() actually does reschedule the task context after
the cgroup changes so the perf cgroup code would need some non-trivial
adjusting to the new APIs.
