From 7b04d7170e9af805cac19f97b28fff10db897893 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Mon, 10 Apr 2006 22:53:27 -0700 Subject: [PATCH] Add GFP_NOWAIT Introduce GFP_NOWAIT, as an alias for GFP_ATOMIC & ~__GFP_HIGH. This also changes XFS, which is the only in-tree user of this idiom that I could find. The XFS piece is compile-tested only.
