Subject: [PATCH 0/3] Use jump_label for sched_feat()
Date: Tue, 06 Dec 2011 18:15:34 +0100 [thread overview]
Message-ID: <20111206171534.429636558@chello.nl> (raw)
These patches implement sched_feat() using jump_labels. The first is a section
mismatch fix. The second patch provides a little infrastructure and the third
patch applies it to make sched_feat() use static_branch().
It uses static_branch() coupled with unlikely/likely in order to control the
branch block position. I haven't checked if it works, but it likely doesn't,
although it should.
