Subject: [PATCH] sched/core: fix sched_rt_global_validate
Date: Fri, 31 Jan 2014 17:43:27 +0100 [thread overview]
Message-ID: <1391186607-11247-1-git-send-email-juri.lelli@gmail.com> (raw)
Don't compare sysctl_sched_rt_runtime against sysctl_sched_rt_period if
the former is equal to RUNTIME_INF, otherwise disabling -rt bandwidth
management always fails.
