Subject: [PATCH 8/9] fsnotify: use BUILD_BUG_ON() to test the weight of ALL_FSNOTIFY_EVENTS
Date: Sat, 16 Mar 2013 00:50:56 +0800 [thread overview]
Message-ID: <1363366257-4886-9-git-send-email-laijs@cn.fujitsu.com> (raw)
In-Reply-To: <1363366257-4886-1-git-send-email-laijs@cn.fujitsu.com>
BUILD_BUG_ON() is build-time-test for constant. avoid runtime test.
also use HWEIGHT32() for build-time.
