Subject[PATCH RFC v2] mpt2/mpt3sas lock reduction for scsi-mq
Date
Hi,

This is v2 of the series. Generally addressed Christoph's review comments,
but more specifically, changes since v1:

- Kill the MPI2_FUNCTION_SCSI_TASK_MGMT support, which in turn
enabled me to drop the SCSI/blk iter patches and the smid work-around
for scsi-mq in mpt2/3 for bumping to hpr for NULL command.
- Made init/exit_command() work (sort of) on non scsi-mq. Drivers
will have to set request_index related information separately
still for non scsi-mq, since we don't have a reliable one
- Use scsi_cmd_priv() instead of adding a new helper.
- Make scsi_find_tag() only return in-progress IO for scsi-mq. This is
simiar to the ->special check for non-mq.
- Ensure that mpt3sas is in sync with the mpt2sas changes.
