From 8a97ea546bb6532f77a0efe165012ee0d0c4b903 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Tue, 10 Apr 2018 16:29:37 -0700 Subject: [PATCH] mm/z3fold.c: use gfpflags_allow_blocking We have a perfectly good macro to determine whether the gfp flags allow you to sleep or not; use it instead of trying to infer it.
