From 2ae88149a27cadf2840e0ab8155bef13be285c03 Mon Sep 17 00:00:00 2001 From: Nick Piggin Date: Sat, 28 Oct 2006 10:38:23 -0700 Subject: [PATCH] mm: clean up pagecache allocation - Consolidate page_cache_alloc - Fix splice: only the pagecache pages and filesystem data need to use mapping_gfp_mask. - Fix grab_cache_page_nowait: same as splice, also honour NUMA placement.
