Subject: kernel/cpuset: current_cpuset_is_being_rebound can be boolean
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=77ef80c65ab72e57cfc273b2dd1d48a282b75146;p=openwrt%2Fstaging%2Fblogic.git

kernel/cpuset: current_cpuset_is_being_rebound can be boolean

Make current_cpuset_is_being_rebound return bool due to this particular
function only using either one or zero as its return value.

No functional change.
