Message-ID: <lsq.1439201551.802115662@decadent.org.uk> Date: Mon, 10 Aug 2015 12:12:31 +0200 From: Ben Hutchings <ben@...adent.org.uk> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org CC: akpm@...ux-foundation.org, "Mike Snitzer" <snitzer@...hat.com>, "Joe Thornber" <ejt@...hat.com> Subject: [PATCH 3.2 071/110] dm btree: silence lockdep lock inversion in dm_btree_del() 3.2.71-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Joe Thornber <ejt@...hat.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.
