Subject: [PATCH 045/290] sched: Disable CONFIG_RT_GROUP_SCHED on RT
|
|
|
|
Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=08989e0969de7b6c4727eb2a32f7c1aaa194708f

Carsten reported problems when running:
|
|
|
|
|
|
|
|
taskset 01 chrt -f 1 sleep 1
|
|
|
|
|
|
|
|
from within rc.local on a F15 machine. The task stays running and
|
|
|
|
never gets on the run queue because some of the run queues have
|
|
|
|
rt_throttled=1 which does not go away. Works nice from a ssh login
|
|
|
|
shell. Disabling CONFIG_RT_GROUP_SCHED solves that as well.
