Subject: [PATCH 1/2] ensure we count pages transitioning inactive via clear_active_flags
Date: Thu, 02 Aug 2007 19:18:12 +0100 [thread overview]
Message-ID: <ee1121744961a5f7350d5b0b97bb2352@pinky> (raw)
In-Reply-To: <exportbomb.1186077923@pinky>
We are transitioning pages from active to inactive in
clear_active_flags, those need counting as PGDEACTIVATE vm events.
