This patch updates the scsi_debug virtual LLD to use root_device_register() and root_device_unregister() from include/linux/device.h instead of device_register() and device_unregister() respectively within scsi_debug_init() and scsi_debug_exit() This simply involved converting the static struct device pseudo_primary into a pointer that is setup by the call to root_device_register(). This patch also contains the correct IS_ERR() conditional check of root_device_register() from within scsi_debug_init(). Thanks to Richard Sharpe and Dmitry Torokhov for their help with this item.

When an rport is "blocked" and a bsg request is received, the bsg request gets placed on the queue but the queue stalls. If the fc object is then deleted - the bsg queue never restarts and keeps the reference on the object, and stops the overall teardown. This patch restarts the bsg queue on teardown and drains any pending requests, allowing the teardown to succeed. Signed-off-by:

Make sure that the rport registration did complete and then register SCSI device directly. Otherwise the unit_enqueue would race with the call to zfcp_scsi_queue_unit_register. Reviewed-by:

The previous thin provisioning support was not very user friendly because it depended on all the relevant options being set on the command line. Implement support for the Thin Provisioning VPD page from SBC3 r24 and add module options for TPU (UNMAP) and TPWS (WRITE SAME (16) with UNMAP bit). This allows us to have sane default and to enable thin provisioning with a simple tpu=1 or tpws=1 on the command line depending on whether we want UNMAP or WRITE SAME behavior. Signed-off-by:

Currently the IOs are returned back in slot reset, this could be late and can cause error handler to invoke. If error handler invokes, eh_abort fails and escalate to device/bus/host resets causing issues. The commands need to be returned back to upper layer in io_error_detected. Signed-off-by:

We have been seeing the flush request timeout with a wide range of hardware from tgt+iser to FC targets from a major vendor. After discussions about if the value should be configurable and what the best value should be, this patch just increases the flush/sync cache timeout to 1 minute. 2 minutes was determined to be too long, and making it configurable was troublesome for users. This patch was made over Linus's tree. It is not made over scsi-misc or scsi-rc-fixes, because Linus's had block layer changes that my patch was built over. Signed-off-by:

In the case when an ep_connect request is interrupted due to route request stall, if the iSCSI daemon is terminated by the user, the chip will be left in a state which will not get cleaned up upon module removal. Upon module reload, when the same context id is used for a new connection, chip panic would occur. This patch adds chip cleanup in the module removal path. Signed-off-by:

VIA VT6306, VIA VT6308, and NEC OrangeLink controllers do not write packet event codes for received PHY packets (or perhaps write evt_no_status, hard to tell). Work around it by overwriting the packet's ACK by ack_complete, so that upper layers that listen to PHY packet reception get to see these packets. (Also tested: TI TSB82AA2, TI TSB43AB22/A, TI XIO2213A, Agere FW643, JMicron JMB381 --- these do not exhibit this bug.) Clemens proposed a quirks flag for that, IOW whitelist known misbehaving controllers for this workaround. Though to me it seems harmless enough to enable for all controllers. The log_ar_at_event() debug log will continue to show the original status from the DMA unit.
