From db507b3ffd9b7a1c87e732ac6e2c3a5d0babb15a Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Mon, 9 Feb 2015 12:21:54 -0500 Subject: [PATCH] dm: fix multipath regression due to initializing wrong request Commit febf715 ("block: require blk_rq_prep_clone() be given an initialized clone request") introduced a regression by calling blk_rq_init() on the original request rather than the clone request that is passed to setup_clone().
