Subject: [PATCH 1/2] mm,oom: Remove unused argument from oom_scan_process_thread().
Date: Sat, 21 May 2016 11:00:41 +0900 [thread overview]
Message-ID: <1463796041-7889-1-git-send-email-penguin-kernel@I-love.SAKURA.ne.jp> (raw)
oom_scan_process_thread() does not use totalpages argument.
oom_badness() uses it.
