From 0888564393a1277ce2d0564d819e1bcff1120343 Mon Sep 17 00:00:00 2001 From: Kiyoshi Ueda Date: Thu, 10 Dec 2009 23:52:15 +0000 Subject: dm: pass gfp_mask to alloc_rq_tio This patch adds the gfp_mask argument to alloc_rq_tio(). No functional change. This patch is a preparation for a later patch in this series which needs to allocate tio (for barrier I/O) with different allocation flag (GFP_NOIO) from the one in the normal I/O code path.
