[PATCH] i2o: block IO errors on i2o disk

2007-03-27T16:05:16+00:00

I2O subsystem has been broken in mainstream several months ago (after
2.6.18).  Commit 4aff5e2333c9a1609662f2091f55c3f6fffdad36 from Jens
Axboe split struct request ->flags into two parts: cmd_type and
cmd_flags.

In i2o layer this patch has replaced flag REQ_SPECIAL by the according
cmd_type.  However i2o has used REQ_SPECIAL not as command type but as
driver-specific flag for the debug purposes.  As result all i2o requests
have type "special" now, are not processed to the hardware and fail with
I/O error:

   i2o/hda:<3>Buffer I/O error on device i2o/hda, logical block 0
  Buffer I/O error on device i2o/hda, logical block 0
  Buffer I/O error on device i2o/hda, logical block 0
   unable to read partition table
  block-osm: device added (TID: 207): i2o/hda

The following patch removes the extra debug checks without any drawbacks and
restores the normal driver's work.

[SCSI] mptsas: Fix oops for insmod during kexec

2007-03-11T15:44:16+00:00

This fix's an oops during driver load time.   mptsas_probe calls
mpt_attach(over in mptbase.c).  Inside that call, we read some
manufacturing config pages to setup some defaults.  While reading the
config pages, the firmware doesn't complete the reply in time, and we
have a timeout. The timeout results in hardreset handler being called.
The hardreset handler calls all the fusion upper layer driver reset
callback handlers.  The mptsas_ioc_reset function is the callback
handler in mptsas.c.   So where I'm getting to, is mptsas_ioc_reset is
getting called before scsi_host_alloc is called, and the pointer ioc->sh
is NULL as well as the hostdata.

[PATCH] remove many unneeded #includes of sched.h

2007-02-14T16:09:54+00:00

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

[PATCH] mark struct file_operations const 5

2007-02-12T17:48:45+00:00

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

form a wide port. Current implementation returns a different address

[SCSI] fusion - serialize target resets in mptsas.c

2007-02-03T03:02:30+00:00

Fusion firmware requires target reset following hotplug removal event,
with purpose to flush target outstanding request in fw. Current implementation
does the target resets from delayed work tasks, that in heavy load
conditions, take too long to be invoked, resulting in command time outs
This patch will issue target reset immediately from ISR context, and will
queue remaining target resets to be issued after the previous one completes.
The delayed work tasks are spawned during the target reset completion.
