[PATCH v2 00/14] cxlflash: Fixes, enhancements, cleanup and staging

[Uma Krishnan]

The first four patches in this patch series include fixes for command
room violation and lun table management.

The remaining patches remove the reliance upon an internally maintained
private command pool in favor of private commands being allocated
alongside the SCSI commands. Several cleanup opportunities were noticed
while removing the private command pool infrastructure and have been
included as well. Lastly, the final two patches provide staging for
supporting hardware with a different queuing model.

The series is based upon 4.9-rc5, intended for 4.10 and is bisectable.
