Add sysfs entries to the cciss driver needed for the dm/multipath tools. A file for vendor, model, rev, and unique_id is added for each logical drive under directory /sys/bus/pci/devices/<dev>/ccissX/cXdY. Where X = the controller (or host) number and Y is the logical drive number. A link from /sys/bus/pci/devices/<dev>/ccissX/cXdY/block:cciss!cXdY to /sys/block/cciss!cXdY/device is also created. A bus is created in /sys/bus/cciss. A link is created from the pci ccissX entry to /sys/bus/cciss/devices/ccissX. Please consider this for inclusion.

Fix the SCSI reset error handler to send a working, properly addressed reset message to the target device and add code to wait for the target device to become ready by polling it with Test Unit Ready. The existing reset code was broken in that it didn't bother to set the 8-byte LUN address to anything besides zero, so the command was addressed to the controller, which pretended to the driver that the command succeeded, while doing nothing. Ages ago I tested this code, but unbeknownst to me, my test was flawed, and what I thought was a tape drive getting reset was actually nothing of the sort. Unfortunately, there is still lots of Smartarray firmware that doesn't handle doing target resets right, and this code won't help in those cases, but it also shouldn't make things worse in those cases than they already are.

Factor out the core of sendcmd() to provide a simpler interface which exposes all the error information to the caller and make the original sendcmd use this new function. Rationale: The SCSI error handling routines need to send commands with interrupts turned off, but they also need access to the full error information. Signed-off-by: NStephen M.

I found one more mis-conversion to the 'request is always dequeued when completing' model in elv_abort_queue() during code inspection. Although I haven't hit any problem caused by this mis-conversion yet and just done compile/boot test, please apply if you have no problem. Request must be dequeued when it completes. However, elv_abort_queue() completes requests without dequeueing. This will cause oops in the __blk_end_request_all(). This patch fixes the oops.

Doing a bit of torture testing, I ran across a BUG in the block subsystem (at blk-core.c:2048): the test for if the request is queued. It turns out the trigger was a BLKPREP_KILL coming out of the SCSI prep function. Currently for BLKPREP_KILL requests, we send them straight into __blk_end_request_all() with an error, but they've never been dequeued, so they trip the bug. Fix this by starting requests before killing them. Signed-off-by: NJames Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

commit e8939a50466fd963eb1ba9118c34b9ffb7ff6aa6 Author: Tejun Heo <tj@kernel.org> Date: Fri May 8 11:54:16 2009 +0900 block: implement and enforce request peek/start/fetch Added a BUG_ON(blk_queued_rq(req)) to the top of blk_finish_req(). Unfortunately, this checks whether req->queuelist is empty. This list is doing double duty both as the queue list and the tag list, so tagged requests come in here with this not empty and boom (the tag list is emptied by blk_queue_end_tag() lower down). Fix this by moving the BUG_ON to below the end tag we also seem vulnerable to this in blk_requeue_request() as well. I think all uses of blk_queued_rq() need auditing because the check is clearly wrong in the tagged case.

To support devices with physical block sizes bigger than 512 bytes we need to ensure proper alignment. This patch adds support for exposing I/O topology characteristics as devices are stacked. logical_block_size is the smallest unit the device can address. physical_block_size indicates the smallest I/O the device can write without incurring a read-modify-write penalty. The io_min parameter is the smallest preferred I/O size reported by the device. In many cases this is the same as the physical block size. However, the io_min parameter can be scaled up when stacking (RAID5 chunk size > physical block size). The io_opt characteristic indicates the optimal I/O size reported by the device. This is usually the stripe width for arrays. The alignment_offset parameter indicates the number of bytes the start of the device/partition is offset from the device's natural alignment. Partition tools and MD/DM utilities can use this to pad their offsets so filesystems start on proper boundaries. Signed-off-by: NMartin K.

Currently stacking devices do not have a queue directory in sysfs. However, many of the I/O characteristics like sector size, maximum request size, etc. are queue properties.

Until now we have had a 1:1 mapping between storage device physical block size and the logical block sized used when addressing the device. With SATA 4KB drives coming out that will no longer be the case. The sector size will be 4KB but the logical block size will remain 512-bytes. Hence we need to distinguish between the physical block size and the logical ditto. This patch renames hardsect_size to logical_block_size. Signed-off-by: NMartin K.

Since 2.6.26 we support UDMA66 on ATAPI devices requiring IVB quirk: commit 8588a2b7 ("ide: add SH-S202J to ivb_list[]") We also later added support for more such devices in: commit e97564f3 ("ide: More TSST drives with broken cable detection") and in: commit 3ced5c49 ("ide: add TSSTcorp CDDVDW SH-S202H to ivb_list[]") It turns out that such devices lack cable detection altogether (which in turn results in incorrect detection of 40-wire cables by our current cable detection strategy) so always handle them by trusting host-side cable detection only. v2: Model detection fixup from Martin.
