From 78ce23b51802f5e917d89e8fc9a56dec6cc2fd5b Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Sun, 31 Jan 2016 17:38:28 -0500 Subject: dm mpath: use blk_mq_alloc_request() and blk_mq_free_request() directly There isn't any need to support both old .request_fn and blk-mq paths in the blk-mq specific portion of __multipath_map(). Call blk_mq_alloc_request() directly rather than use blk_get_request(). Similarly, call blk_mq_free_request(), rather than blk_put_request(), in multipath_release_clone().
