From c62d25556be6c965dc14288e796a576e8e39a7e9 Mon Sep 17 00:00:00 2001 From: Michal Hocko Date: Fri, 6 Nov 2015 16:28:49 -0800 Subject: mm, fs: introduce mapping_gfp_constraint() There are many places which use mapping_gfp_mask to restrict a more generic gfp mask which would be used for allocations which are not directly related to the page cache but they are performed in the same context. Let's introduce a helper function which makes the restriction explicit and easier to track. This patch doesn't introduce any functional changes.
