Message-Id: <1513047319-22302-5-git-send-email-baiyaowei@cmss.chinamobile.com> Date: Mon, 11 Dec 2017 21:55:15 -0500 From: Yaowei Bai <baiyaowei@...s.chinamobile.com> To: akpm@...ux-foundation.org Cc: linux-kernel@...r.kernel.org, baiyaowei@...s.chinamobile.com Subject: [PATCH 4/8] kernel/cpuset: current_cpuset_is_being_rebound can be boolean This patch makes current_cpuset_is_being_rebound return bool due to this particular function only using either one or zero as its return value.
