Subject: sched/fair: Change prefer_sibling type to bool
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2cce4ee7186ffd7028b2a0053590d98a0d50c830;p=platform%2Fkernel%2Flinux-exynos.git

sched/fair: Change prefer_sibling type to bool

This variable is entirely local to update_sd_lb_stats, so we can
safely change its type and slightly clean up its initialisation.
