3.2.71-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Joe Thornber <e...@redhat.com>
commit 1c7518794a3647eb345d59ee52844e8a40405198 upstream.
Allocate memory using GFP_NOIO when deleting a btree. dm_btree_del()
can be called via an ioctl and we don't want to recurse into the FS or
block layer.
