Subject: [RFC][PATCH 0/9] perf: Rework event scheduling
Date: Sat, 09 Apr 2011 21:17:39 +0200 [thread overview]
Message-ID: <20110409191739.813727025@chello.nl> (raw)
This series is a broken out and tested version of a patch I proposed in
an earlier thread with Jiri and Oleg:
https://lkml.org/lkml/2011/3/31/232
I've not yet gone over the final patch enough to convince myself we can indeed
re-enable the jump_label optimization of the sched_out hook, but at least the
patches are reasonably readable and result in a working kernel (as opposed to
the earlier posting).
Also still to do is look at the cgroup event scheduling code which currently
also violates our event scheduling rules.
