Message-Id: <1409848265-17150-17-git-send-email-klamm@yandex-team.ru> Date: Thu, 4 Sep 2014 20:31:03 +0400 From: klamm@...dex-team.ru To: peterz@...radead.org, mingo@...hat.com, linux-kernel@...r.kernel.org Cc: stfomichev@...dex-team.ru, Roman Gushchin <klamm@...dex-team.ru> Subject: [PATCH 17/19] smart: disable RT runtime sharing From: Roman Gushchin <klamm@...dex-team.ru> This patch disables runtime sharing for rt tasks (RT_RUNTIME_SHARE). It's necessary to guarantee that CFS tasks (including system threads like rcu workers) will get time slice regularly on each cpu even when system is heavily loaded with rt tasks.
