----------------------------------------------------------------
- Fix DM integrity shrink crash due to journal entry not being marked unused.

- Fix DM bio polling to handle possibility that underlying device(s) return BLK_STS_AGAIN during submission.

- Fix dm_io and dm_target_io flags race condition on Alpha.

- Add some pr_err debugging to help debug cases when DM ioctl structure is corrupted.
