Please pull, thanks.

----------------------------------------------------------------
- Add DM verity support for signature verification with 2nd keyring.

- Fix DM verity to skip verity work if IO completes with error while
  system is shutting down.

- Add new DM multipath "IO affinity" path selector that maps IO
  destined to a given path to a specific CPU based on user provided
  mapping.

- Rename DM multipath path selector source files to have "dm-ps"
  prefix.

- Add REQ_NOWAIT support to some other simple DM targets that don't
  block in more elaborate ways waiting for IO.

- Export DM crypt's kcryptd workqueue via sysfs (WQ_SYSFS).

- Fix error return code in DM's target_message() if empty message is
  received.

- A handful of other small cleanups.
