Date: Mon, 10 Feb 2014 16:36:53 +0100 From: Nicholas Mc Guire <der.herr@...r.at> To: linux-rt-users@...r.kernel.org Cc: LKML <linux-kernel@...r.kernel.org>, Sebastian Andrzej Siewior <bigeasy@...utronix.de>, Steven Rostedt <rostedt@...dmis.org>, Peter Zijlstra <peterz@...radead.org>, Carsten Emde <C.Emde@...dl.org>, Thomas Gleixner <tglx@...utronix.de>, Andreas Platschek <platschek@....tuwien.ac.at> Subject: [PATCH RT 0/5] preempt_disable/enable -> migrate_disable/enable pushdown proposals a small series of preempt_disable/enable -> migrate_disable/enable pushdown proposals In mainline a number of preempt_disable/enable are actually topology control and not actual concurrency control - these cases can be pushed down to a preemptible migrate_disable/enable. This little series contains a few pushdowns from preempt_disable to migrate_disable where code pattern scans using cocci scripts suggested this to be possible. The cases detected were then reviewed and tested with the migrate_disable/enable respectively with the preempt_disable/enable completely removed in one case. Testing was done but is of very limited use for locking/migration related issues, so a review of the code analysis/rational is requested along with additional testing. thx! hofrat -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
