[SCSI] SCSI sd: fix module init/exit error handling

2006-10-04T18:14:16+00:00

- Properly handle and unwind errors in init_sd().  Fixes leaks on error,
  if class_register() or scsi_register_driver() failed.

- Ensure that exit_sd() execution order is the perfect inverse of
  initialization order.

FIXME:  If some-but-not-all register_blkdev() calls fail, we wind up
calling unregister_blkdev() for block devices we did not register.
This was a pre-existing bug.

[PATCH] Split struct request ->flags into two parts

2006-09-30T18:23:37+00:00

Right now ->flags is a bit of a mess: some are request types, and
others are just modifiers. Clean this up by splitting it into
->cmd_type and ->cmd_flags. This allows introduction of generic
Linux block message types, useful for sending generic Linux commands
to block devices.

[SCSI] Wrong size information for devices with disabled read access

2006-09-02T18:37:47+00:00

When accessing a device with disabled read access the capacity is set
randomly to 1GB. This makes it impossible to userspace tools to detect
invalid device capacities.

[SCSI] hide EH backup data outside the scsi_cmnd

2006-07-09T16:56:44+00:00

Currently struct scsi_cmnd has various fields that are used to backup
original data after the corresponding fields have been overridden for
EH commands.  This means drivers can easily get at it and misuse it.
Due to the old_ naming this doesn't happen for most of them, but two
that have different names have been used wrong a lot (see previous
patch).  Another downside is that they unessecarily bloat the scsi_cmnd
size.

This patch moves them onstack in scsi_send_eh_cmnd to fix those two
issues aswell as allowing future EH fixes like moving the EH command
submissions to use SG lists like everything else.

[SCSI] scsi: Add allow_restart sysfs class attribute

2006-06-28T16:39:06+00:00

This is a resend of a patch I generated in response to an email sent
by Ruben Faelens . His original email to
linux-scsi requested a method in which he could spin down a scsi disk
when not in use and have the kernel automatically spin it back up when
an I/O was generated to the disk. The infrastructure to automatically
spin a disk up has been in the scsi error handler for some time now,
but it is not enabled by default. This patch adds an sd sysfs attribute
which allows userspace to enable this behavior.

[SCSI] sd/scsi_lib simplify sd_rw_intr and scsi_io_completion

2006-06-26T15:00:20+00:00

This patch simplifies "good_bytes" computation in sd_rw_intr().
sd: "good_bytes" computation is always done in terms of the resolution
of the device's medium, since after that it is the number of good bytes
we pass around and other layers/contexts (as opposed ot sd) can translate
that to their own resolution (block layer:512).  It also makes
scsi_io_completion() processing more straightforward, eliminating the
3rd argument to the function.

It also fixes a couple of bugs like not checking return value,
using "break" instead of "return;", etc.

I've been running with this patch for some time now on a
test (do-it-all) system.

[SCSI] drivers/scsi: Use ARRAY_SIZE macro

2006-06-10T15:45:30+00:00

Use ARRAY_SIZE macro instead of sizeof(x)/sizeof(x[0]) and remove
duplicates of the macro.
