From 0c4de0f33b0a86a426c0c3958cd40d8c82ede8d2 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 19 Jul 2016 11:31:50 +0200 Subject: block: ensure bios return from blk_get_request are properly initialized blk_get_request is used for BLOCK_PC and similar passthrough requests. Currently we always need to call blk_rq_set_block_pc or an open coded version of it to allow appending bios using the request mapping helpers later on, which is a somewhat awkward API. Instead move the initialization part of blk_rq_set_block_pc into blk_get_request, so that we always have a safe to use request.
