From 6165572c1139dd694afb8e382a5f06e7e0fa4ad8 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Thu, 15 Jun 2017 17:16:43 +0200 Subject: [PATCH] btrfs: use GFP_KERNEL in btrfs_init_dev_replace_tgtdev The function is called from ioctl context and we don't hold any locks that take part in writeback. Right now it's only fs_info::volume_mutex.
