Message-Id: <1444277879-22039-1-git-send-email-dave@stgolabs.net> Date: Wed, 7 Oct 2015 21:17:59 -0700 From: Davidlohr Bueso <dave@...olabs.net> To: Andrew Morton <akpm@...ux-foundation.org> Cc: linux-mm@...ck.org, linux-kernel@...r.kernel.org, Davidlohr Bueso <dave@...olabs.net>, Davidlohr Bueso <dbueso@...e.de> Subject: [PATCH -next] mm/vmacache: inline vmacache_valid_mm() This function incurs in very hot paths and merely does a few loads for validity check. Lets inline it, such that we can save the function call overhead.
