From: Joe Thornber <ejt@xxxxxxxxxx> 3.4.111-rc1 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.
