With the cfq_queue hash removal, we inadvertently got rid of the async queue sharing. This was not intentional, in fact CFQ purposely shares the async queue per priority level to get good merging for async writes. So put some logic in cfq_get_queue() to track the shared queues.

They are all broken beyond repair. Given that nobody has complained about them (most haven't worked in 2.6 AT ALL), remove them from the tree. A new mitsumi driver that actually works is in progress, it'll get added when completed. Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

- I have unearthed very old bugs in stale drivers that still used request->cmd as a READ|WRITE int - This patch is maybe a proof that these drivers have not been used for a long time.

Barrier bios are completed twice - once after the barrier write itself is done and again after the whole sequence is complete. flush_dry_bio_endio() is for the first completion. It doesn't really complete the bio. It rewinds bvec and resets bio so that it can be completed again when the whole barrier sequence is complete. The bvec rewinding code has the following problems. 1. The rewinding code is wrong because filesystems may pass bvec with non zero bv_offset. 2. The block layer doesn't guarantee anything about the state of bvec array on request completion. bv_offset and len are updated iff __end_that_request_first() completes the bvec partially. Because of #2, #1 doesn't really matter (nobody cares whether bvec is re-wound correctly or not) but then again by not doing unwinding at all, we'll always give back the same bvec to the caller as full bvec completion doesn't alter bvecs and the final completion is always full completion. Drop unnecessary rewinding code. This is spotted by Neil Brown. Signed-off-by: NTejun Heo <htejun@gmail.com> Cc: Neil Brown <neilb@suse.de> Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

Two bugs in there: - The virt oversize check should use the current bio hardware back size and the next bio front size, not the same bio.

Add rudimentary check for the case that the page table overflows due to merging of s/g elements by the IOMMU. This would have lead to overwriting of arbitrary memory. After this change I expect that an offending command will be unsuccessfully retried until the scsi_device is taken offline by SCSI core. It's a border case and not worth to implement a recovery strategy. Signed-off-by: NStefan Richter <stefanr@s5r6.in-berlin.de> Acked-by: NKristian Høgsberg <krh@redhat.com>

Use a speed probe to determine the speed over 1394b buses and of nodes which report a link speed less than their PHY speed. Log the effective maximum speed of newly created nodes in dmesg. Also, read the config ROM (except bus info block) at the maximum speed rather than S100. This isn't a real optimization though because we still only use quadlet read requests for the entire ROM. The patch also adds support for S1600 and S3200, although such hardware does not exist yet.

Based on patch "the scheduled removal of RAW1394_REQ_ISO_{SEND,LISTEN}" from Adrian Bunk, November 20 2006. This patch also removes the underlying facilities in ohci1394 and disables them in pcilynx. That is, hpsb_host_driver.devctl() and hpsb_host_driver.transmit_packet() are no longer used for iso reception and transmission. Since video1394 and dv1394 only work with ohci1394 and raw1394's rawiso interface has never been implemented in pcilynx, pcilynx is now no longer useful for isochronous applications. raw1394 will still handle the request types but will complete the requests with errors that indicate API version conflicts.

After ieee1394 was converted away from class_device like the networking subsystem was already in 2.6.21, eth1394's device may point to the fw-host device as its parent again like in 2.6.20.

Remove the global nodemgr_serialize mutex which enclosed most of the host thread event loop. This allows for parallelism between several host adapter cards. Properly serialize the driver hooks .update(), .suspend(), .resume(), and .remove() by means of device->sem. These hooks can be called from outside the host threads' contexts. Get() and put() the device.driver when calling its hooks. Signed-off-by: NStefan Richter <stefanr@s5r6.in-berlin.de>
