a) TYPE_SDAD renamed to TYPE_RBC and taken to scsi.h b) in sbp2.c remapping of TYPE_RPB to TYPE_DISK turned off c) relevant places in midlayer and sd.c taught to accept TYPE_RBC d) sd.c::sd_read_cache_type() looks into page 6 when dealing with TYPE_RBC - these guys have writeback cache flag there and are not guaranteed to have page 8 at all. e) sd_read_cache_type() got an extra sanity check - it checks that it got the page it asked for before using its contents. And screams if mismatch had happened. Rationale: there are broken devices out there that are "helpful" enough to go for "I don't have a page you've asked for, here, have another one". For example, PL3507 had been caught doing just that... f) sbp2 sets sdev->use_10_for_rw and sdev->use_10_for_ms instead of bothering to remap READ6/WRITE6/MOD_SENSE, so most of the conversions in there are gone now. Incidentally, I wonder if USB storage devices that have no mode page 8 are simply RBC ones. I haven't touched that, but it might be interesting to check... Signed-off-by:

New code from the Adaptec driver. Performance enhancement for newer adapters. I hope that this isn't too big for a single patch. I believe that other than the few small cleanups mentioned, that the changes are all related. - Added Variable FIB size negotiation for new adapters. - Added support to maximize scatter gather tables and thus permit requests larger than 64KB/each. - Limit Scatter Gather to 34 elements for ROMB platforms. - aac_printf is only enabled with AAC_QUIRK_34SG - Large FIB ioctl support - some minor cleanup Passes sparse check. I have tested it on x86 and ppc64 machines. Signed-off-by: -

Save and restore the scmd->result, so that timed out commands do not return the result of the TEST UNIT READY or the start/stop commands. Code is already in place to save and restore the result for the request sense case. The previous version of this patch erroneously removed the "if" check, instead add a comment as to why the "if" is needed. Signed-off-by:

scsi_queue_insert() has four callers. Three callers call with timer disabled and one (the second invocation in scsi_dispatch_cmd()) calls with timer activated. scsi_queue_insert() used to always call scsi_delete_timer() and ignore the return value. This results in race with timer expiration. Remove scsi_delete_timer() call from scsi_queue_insert() and make the caller delete timer and check the return value. Signed-off-by:

Currently, during PCI hotplug remove, if the upper layer drivers of the attached devices send commands down as part of the remove action, like a CDROM, the hotplug action will hang forever due to the ipr driver returning SCSI_MLQUEUE_HOST_BUSY. Patch fixes this. Signed-off-by:

This patch addresses the sparse -Wbitwise warnings that Christoph wanted me to eliminate. This mostly consisted of making data structure elements of hardware associated structures the __le* equivalent. Although there were a couple places where there was mixing of cpu and le variable math. These changes have been tested on both an x86 and ppc machine running bonnie++. The usage of the LE32_ALL_ONES macro has been eliminated. Signed-off-by:

scsi_queue_insert() used to use blk_insert_request() for requeueing requests. This depends on the unobvious behavior of blk_insert_request() setting REQ_SPECIAL and REQ_SOFTBARRIER when requeueing. This patch makes scsi_queue_insert() use blk_requeue_request(). As REQ_SPECIAL means special requests and REQ_SOFTBARRIER is automatically handled by blk layer now, no flag needs to be set. Note that scsi_queue_insert() now calls scsi_run_queue() itself, and the prototype of the function is added right above scsi_queue_insert(). This is temporary, as later requeue path consolidation patchset removes scsi_queue_insert(). By adding temporary prototype, we can do away with unnecessarily moving functions. Signed-off-by:

blk_insert_request() has a unobivous feature of requeuing a request setting REQ_SPECIAL|REQ_SOFTBARRIER. SCSI midlayer was the only user and as previous patches removed the usage, remove the feature from blk_insert_request(). Only special requests should be queued with blk_insert_request(). All requeueing should go through blk_requeue_request(). Signed-off-by:
