From 8395cd9f813d5d7ed9870e642230acfcfc1e8a0a Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 22 May 2015 17:13:34 -0400 Subject: [PATCH] writeback: add @gfp to wb_init() wb_init() currently always uses GFP_KERNEL but the planned cgroup writeback support needs using other allocation masks. Add @gfp to wb_init(). This patch doesn't introduce any behavior changes.
