Subject: [RFC][PATCH 00/11] sched: Killing PREEMPT_ACTIVE
Date: Tue, 29 Sep 2015 11:28:25 +0200 [thread overview]
Message-ID: <20150929092825.540553633@infradead.org> (raw)
This series kills PREEMPT_ACTIVE dead, its a tad risky, but survives light
testing on x86_64 and seems to compile on everything else.
