From f27b087b81b70513b8c61ec20596c868f7b93474 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Fri, 6 Jun 2014 07:57:37 -0600 Subject: block: add blk_rq_set_block_pc() With the optimizations around not clearing the full request at alloc time, we are leaving some of the needed init for REQ_TYPE_BLOCK_PC up to the user allocating the request. Add a blk_rq_set_block_pc() that sets the command type to REQ_TYPE_BLOCK_PC, and properly initializes the members associated with this type of request. Update callers to use this function instead of manipulating rq->cmd_type directly. Includes fixes from Christoph Hellwig for my half-assed attempt.
