Subject: [PATCH RT 09/24] Revert "timer: delay waking softirqs from the jiffy tick"
Date: Fri, 07 Sep 2018 16:59:06 -0400 [thread overview]
Message-ID: <20180907205931.097824414@goodmis.org> (raw)
In-Reply-To: 20180907205857.262840394@goodmis.org
4.14.63-rt41-rc2 stable review patch.
If anyone has any objections, please let me know.
------------------
From: Anna-Maria Gleixner <anna-maria@linutronix.de>
[ Upstream commit b5b16907c58280e015d5673dca4c6bd3fde0c348 ]
This patch was required as long as RT tasks where accounted to CFS
load but this was only a work around. Upstream Commit 17bdcf949d03
("sched: Drop all load weight manipulation for RT tasks") fixed the
accounting of RT tasks into CFS load.
Remove the patch and fix dependencies.
