From a3bce90edd8f6cafe3f63b1a943800792e830178 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Thu, 28 Aug 2008 16:17:05 +0900 Subject: block: add gfp_mask argument to blk_rq_map_user and blk_rq_map_user_iov Currently, blk_rq_map_user and blk_rq_map_user_iov always do GFP_KERNEL allocation. This adds gfp_mask argument to blk_rq_map_user and blk_rq_map_user_iov so sg can use it (sg always does GFP_ATOMIC allocation).
