ub: Ignore bad residue

2008-05-02T17:25:52+00:00

I hoped to continue to ignore this problem or use libusual, but these
days it's simpler to work around than to deal with it. Let's attempt to
use bad residue devices and hope that upper level integrity checks catch
any problems (e.g. please use sha1sum on your backups).

ub: Fix timeouts

2008-05-02T17:25:52+00:00

The wodim says:
"close track/session scsi sendcmd: cmd timeout after 5.000 (480) s"
This happened because we ignored the supplied timeout and used 5s.

It's not completely correct to apply a timeout meant for the complete
command to any single URB, but we don't have many URBs per command, so
this is simple and works.

block: make queue flags non-atomic

2008-04-29T12:48:33+00:00

We can save some atomic ops in the IO path, if we clearly define
the rules of how to modify the queue flags.

ub: remove BUG() after __blk_end_request and fix the condition causing it

2008-04-09T01:25:52+00:00

When __blk_end_request returns nonzero, it means that the request was
not completely processed and some BIOs are still attached. Since we
have dequeued it by that time, it means leaking requests and hanging
processes, which is why BUG() was in there. In ub this happens if
a packet request ends normally, but with residue (e.g. when scsi_id
issues INQUIRY).

The fix is to make sure that arguments passed to __blk_end_request
are correct: the full request length and not just transferred length.
The transferred length is indicated to applications by adjusting
rq->data_len with old, unchanged code outside of this patch.

USB: Remove unnecessary zeroing from ub

2008-02-01T22:34:47+00:00

These zeroings were taken from usb-storage long time ago. I examined
the submission paths and usb_fill_bulk_urb and found them unnecessary.
