Merge patch series "scsi_debug: Some minor improvements"

John Garry <john.g.garry@oracle.com> says:

This series contains a bunch of minor improvements to the driver. I
have another bunch waiting with more major changes.

Most of the changes are quite straightforward, and the only patches of
note are as follows:

 - Fix the command abort feature, enabled with host option
   SDEBUG_OPT_CMD_ABORT.

 - Drop driver count of queued commands per device.

 - Add poll mode completions to statistics. We already have poll mode
   callback call count, so maybe it was intentional to omit poll mode
   from the statistics.
