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.
