Pull device mapper fixes from Mike Snitzer: - a couple DM raid and DM mirror fixes - a couple .request_fn request-based DM NULL pointer fixes - a fix for a DM target reference count leak, on target load error, that prevented associated DM target kernel module(s) from being removed * tag 'dm-4.9-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm table: fix missing dm_put_target_type() in dm_table_add_target() dm rq: clear kworker_task if kthread_run() returned an error dm: free io_barrier after blk_cleanup_queue call dm raid: fix activation of existing raid4/10 devices dm mirror: use all available legs on multiple failures dm mirror: fix read error on recovery after default leg failure dm raid: fix compat_features validation
