Merge tag 'for-4.13/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper updates from Mike Snitzer: - Add the ability to use select or poll /dev/mapper/control to wait for events from multiple DM devices. - Convert DM's printk macros over to using pr_<level> macros. - Add a big-endian variant of plain64 IV to dm-crypt. - Add support for zoned (aka SMR) devices to DM core. DM kcopyd was also improved to provide a sequential write feature needed by zoned devices. - Introduce DM zoned target that provides support for host-managed zoned devices, the result dm-zoned device acts as a drive-managed interface to the underlying host-managed device. - A DM raid fix to avoid using BUG() for error handling. * tag 'for-4.13/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm zoned: fix overflow when converting zone ID to sectors dm raid: stop using BUG() in __rdev_sectors() dm zoned: drive-managed zoned block device target dm kcopyd: add sequential write feature dm linear: add support for zoned block devices dm flakey: add support for zoned block devices dm: introduce dm_remap_zone_report() dm: fix REQ_OP_ZONE_REPORT bio handling dm: fix REQ_OP_ZONE_RESET bio handling dm table: add zoned block devices validation dm: convert DM printk macros to pr_<level> macros dm crypt: add big-endian variant of plain64 IV dm bio prison: use rb_entry() rather than container_of() dm ioctl: report event number in DM_LIST_DEVICES dm ioctl: add a new DM_DEV_ARM_POLL ioctl dm: add basic support for using the select or poll function
