From 41e9b63b35b52cf918a4ffdb8d77862ab824aa8b Mon Sep 17 00:00:00 2001 From: Nick Piggin Date: Fri, 6 Jan 2006 00:11:13 -0800 Subject: [PATCH] mm: pfault optimisation This atomic operation is superfluous: the pte will be added with the referenced bit set, and the page will be referenced through this mapping after the page fault handler returns anyway.
