From: Joe Thornber <ejt@redhat.com> 3.12-stable review patch. If anyone has any objections, please let me know. =============== 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.
