dm cache: simplify the return expression of load_mapping() (2020-12-22 09:54:48 -0500)

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.
