[SCSI] tmscsim: remove bogus endianness conversions · 46e5ba2b

Guennadi Liakhovetski authored May 04, 2007

cpu_to_le32 endianness conversions in tmscsim.c, followed by
arithmetic operations don't look correct. Besides, {in,out}[wl]
already perform the necessary conversions. Further, bus addresses
of request buffers are guaranteed to be (mapped) under 4G by
current scsi- and block-layer defaults. This could be explicitly
enforced by using blk_queue_bounce_limit(), which, however,
doesn't seem to be the common practice among SCSI drivers.

[SCSI] ipr: Better handle adapter boot time errors · 473b1e8e

Brian King authored May 02, 2007

If an ipr adapter encounters an adapter error requiring an
adapter reset to recover from prior to driver load time, the
error will be ignored and recovery will not happen until the
initial timeout occurs waiting for the firmware to come ready,
which means a five minute timeout. Fix is to read the interrupt
register before clearing any of the interrupts at probe time.

[SCSI] deprecate the old NCR53C9x driver · a6bcbc2f

Christoph Hellwig authored Apr 30, 2007

Now that we have the much better esp_scsi driver and low level drivers
are easy to port over deprecate the old NCR53C9x driver.

I've Cc'ed the m68k and mips lists because all but one bus glues are
for these platforms. Chances stand bad for the remaining driver,
mca_53c9x which hasn't gotten any non-trivial update since it was
merge in late 2.1.x and whos maintainers mail address bounces.

[SCSI] fc_transport: make all rports wait dev_loss_tmo before removing them · 92740b24

James Smart authored Apr 27, 2007

Per the comment in the change - it's not always prudent to immediately
remove the rport upon first notice of a disconnect. Make all rports
wait dev_loss_tmo before being deleted (and each could have a separate
dev_loss_tmo value).

The original post was:
http://marc.info/?l=linux-scsi&m=117392196006703&w=2

The repost contains the following changes:
 - Bug fix in fc_starget_delete(). Dev_loss_tmo_callbk() was called prior to
   tearing down the target. The callback is to be the last thing called, as
   it tells the LLDD that the rport is completely finished and can be torn
   down.  Rework so that terminate_rport_io() is called to terminate the
   outstanding io. Isolated work so it's is simply "starget" work.
 - Fix holes in original patch. There were code paths that did not expect
   the dev_loss_tmo timer to be running for the non-fcp rports.
 - Bug Fix: the transport wasn't protecting against a LLDD calling
   fc_remote_port_delete() back-to-back. Thus, the dev_loss_tmo timer
   could be restarted such that it fires after the rport had been deleted.
   Validate rport state before starting the timer.
