Subject: sched: Don't scan all-offline ->cpus_allowed twice if !CONFIG_CPUSETS
X-Git-Tag: KARO-TX6UL-2015-11-03~56^2~14^2
X-Git-Url: https://git.kernelconcepts.de/?p=karo-tx-linux.git;a=commitdiff_plain;h=e73e85f0593832aa583b252f9a16cf90ed6d30fa;hp=e73e85f0593832aa583b252f9a16cf90ed6d30fa

sched: Don't scan all-offline ->cpus_allowed twice if !CONFIG_CPUSETS

If CONFIG_CPUSETS=n then "case cpuset" changes the state and runs
the already failed for_each_cpu() loop again for no reason.
