This is because usb_reset_device now unbinds, and that calls disconnect,
which in case of ub waits until the reset completes... which deadlocks.
Worse, this deadlocks keventd and this takes whole box down.

I'm going to fix this properly later, but let's unbreak the driver
quickly for non-composite devices at least.

This regression was introduced by commit
6ae5ce8e8d ("cciss: remove redundant code").

This patch fixes a regression where the controller firmware version is not

Mike Miller 404443081c cciss: fix sysfs broken symlink regression
Regression introduced by commit 6ae5ce8e8d
("cciss: remove redundant code").

This patch fixes a broken symlink in sysfs that was introduced by the
above commit.  We broke it in 2.6.27-rc on or about 20080804.  Some
installers are broken if this symlink does not exist and they may not
detect the logical drives configured on the controller.  It does not
require being backported into 2.6.26.x or earlier kernels.

Al Viro d4430d62fa [PATCH] beginning of methods conversion
To keep the size of changesets sane we split the switch by drivers;
to keep the damn thing bisectable we do the following:
	1) rename the affected methods, add ones with correct
prototypes, make (few) callers handle both.  That's this changeset.
	2) for each driver convert to new methods.  *ALL* drivers
are converted in this series.
	3) kill the old (renamed) methods.

Note that it _is_ a flagday; all in-tree drivers are converted and by the
end of this series no trace of old methods remain.  The only reason why
we do that this way is to keep the damn thing bisectable and allow per-driver
debugging if anything goes wrong.

New methods:
	open(bdev, mode)
	release(disk, mode)
	ioctl(bdev, mode, cmd, arg)		/* Called without BKL */
	compat_ioctl(bdev, mode, cmd, arg)
	locked_ioctl(bdev, mode, cmd, arg)	/* Called with BKL, legacy */

Parag Warudkar 01e8ef11bc x86: sysfs: kill owner field from attribute
Tejun's commit 7b595756ec made sysfs
attribute->owner unnecessary.  But the field was left in the structure to
ease the merge.  It's been over a year since that change and it is now
time to start killing attribute->owner along with its users - one arch at
a time!

This patch is attempt #1 to get rid of attribute->owner only for
CONFIG_X86_64 or CONFIG_X86_32 .  We will deal with other arches later on
as and when possible - avr32 will be the next since that is something I
can test.  Compile (make allyesconfig / make allmodconfig / custom config)
and boot tested.

akpm: the idea is that we put the declaration of sttribute.owner inside
`#ifndef CONFIG_X86'.  But that proved to be too ambitious for now because
new usages kept on turning up in subsystem trees.
