[SCSI] scsi_dh: fix reference counting in scsi_dh_activate error path

2011-04-24T16:02:09+00:00

Commit db422318cbca55168cf965f655471dbf8be82433 ([SCSI] scsi_dh:
propagate SCSI device deletion) introduced a regression where the device
reference is not dropped prior to scsi_dh_activate's early return from
the error path.

[SCSI] scsi_dh_rdac : Adding MODULE VERSION for rdac device handler

2011-02-12T20:14:11+00:00

Adding MODULE_VERSION for scsi_dh_rdac. This will be helpful sometimes
to get the code level without looking at the code.

[SCSI] scsi_dh: cosmetic change to sizeof()

2011-02-12T20:13:34+00:00

instead of doing sizeof(struct X) it's better to do sizeof(*v) where v
is the variable pointing to struct X.

[SCSI] scsi_dh_rdac: fix for lun_table update for rdac device handler

2011-02-12T20:05:08+00:00

During one of our testing, we noticed that mode select command sent
from the host did not have the lun_table updated.

Problem is root caused to the way lun table is updated. Lun table
update was done after the call to blk_rq_map_kern is made. This was
causing problem because kernel uses bounce buffer(bio_copy_kern) if
the address is not aligned.  The command buffer updated after the
call(blk_rq_map_kern) was not going on the wire. Moved the code to
update the lun_table before the call to fix the problem.

[SCSI] scsi_dh_hp_sw: fix deadlock in start_stop_endio

2011-02-12T16:31:04+00:00

The use of blk_execute_rq_nowait() implies __blk_put_request() is needed
in start_stop_endio() rather than blk_put_request() --
blk_finish_request() is called with queue lock already held.

[SCSI] scsi_dh: Use scsi_devinfo functions to do matching of device_handler tables.

2011-01-24T18:02:09+00:00

Previously we were using strncmp in order to avoid having to include
whitespace in the devlist, but this means "HSV1000" matches a device
list entry that says "HSV100", which is wrong.  This patch changes
scsi_dh.c to use scsi_devinfo's matching functions instead, since they
handle these cases correctly.

[SCSI] scsi_dh_alua: add scalable ONTAP lun to dev list

2011-01-24T17:13:48+00:00

Currently NetApp's VID/PID details in the INQUIRY response shows up as
'NETAPP' and 'LUN'.  With upcoming scalable SAN ONTAP version on NetApp
controllers, the PID entry alone is being modified to 'LUN C-Mode' (to
distinguish current ONTAP LUNs from scalable ONTAP LUNs).

'LUN' would still suffice for matching 'LUN C-Mode' but best to
explicitly add these new NetApp LUNs to the device list.
