83021920e7 [PATCH] qla2xxx: cleanup DMA mappings...
Don't use cmd->request->nr_hw_segments as it may not be initialized
  (SG_IO in particular bypasses anything that initializes this and just
  uses scsi_do_req to insert a scsi_request directly on the head of the
  queue) and a bogus value here can trip up the checks to make sure that
  the number of segments will fit in the queue ring buffer, resulting in
  commands that are never completed.

  Fix up several issues with PCI DMA mapping and failure to check return
  values on the mappings.

  Make the check for space in the ring buffer happen after the DMA mapping
  is done since any checks done before the mapping has taken place are
  bogus.

Add initial support for FC remote port infrastructure.

     o Use fc_remote_port...() registration and block/unlock
       functions.
     o Consolidate 'attribute' (fc-remote/sysfs) helpers into
       new qla_attr.c file.

f4f051ebb4 [PATCH] qla2xxx: remove internal queuing...
Remove internal command queuing from the driver.  As is, this
driver cannot tolerate cable-pulls as I/Os will begin to fail
by the upper layers.

     o Should be used in conjuction with the
       11-fc_rport_adds_2.diff patch.
     o Removes qla_listops.h file -- no longer needed.

bf341919db scsi: add DID_REQUEUE to the error handling
We have a DID_IMM_RETRY to require a retry at once, but we could do with
a DID_REQUEUE to instruct the mid-layer to treat this command in the
same manner as QUEUE_FULL or BUSY (i.e. halt the submission until
another command returns ... or the queue pressure builds if there are no
outstanding commands).

2bc474c364 [PATCH] kill old EH constants
Fix up two drivers that incorrectly were using the old return values for
their new-style EH methods and kill off scsi_obsolete.h that defined the
constants.  The initio driver has all these constansts defined locally
and uses them internally, I'll fix that up some time later.

c6295cdf65 [PATCH] scsi: remove meaningless scsi_cmnd->serial_number_at_timeout field
scsi_cmnd->serial_number_at_timeout doesn't serve any purpose
anymore.  All serial_number == serial_number_at_timeout tests
are always true in abort callbacks.  Kill the field.  Also, as
->pid always equals ->serial_number and ->serial_number
doesn't have any special meaning anymore, update comments
above ->serial_number accordingly.  Once we remove all uses of
this field from all lldd's, this field should go.

c2a9331c62 updates for CFQ oops fix
- add a comment to the device structure that the device_busy field
  is now protected by the request_queue->queue_lock
- null out sdev->request_queue after the queue is released to trap
  any (and there shouldn't be any) use after the queue is freed.

152587deb8 [PATCH] fix NMI lockup with CFQ scheduler
The current problem seen is that the queue lock is actually in the
SCSI device structure, so when that structure is freed on device
release, we go boom if the queue tries to access the lock again.

The fix here is to move the lock from the scsi_device to the queue.

cb59e84083 [PATCH] sg.c: update
The attachment combines the most recent patch from
Yum Rayan <yum.rayan@gmail.com> (to reduce sg stack
usage), Adrian Bunk <bunk@stusta.de> (to fix check
after use) and me (fix elapsed time calculation
(duration) on ia64 machines).

I have modified the patch from Yum Rayan so kmalloc()
in sg_read() is only called for the (rare) code paths
that need them.

Changelog:
   - reduce stack usage in sg_ioctl() and sg_read()
   - fix check after use in sg_mmap()
   - hold duration internally in milliseconds and
     check current time later than held time

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
