Here are two patches against your 2.6.26-rc2-git tree.

They do:
	- remove an unused list head in struct class now that struct
	  class_device is gone.
	- fix a bug at boot time with raid partitions.  This is a
	  regression from 2.6.24 that is now finally fixed.  Many thanks
	  to Kay for doing this work.  It will be added to the
	  2.6.25-stable tree as well.

Please pull from:
	master.kernel.org:/pub/scm/linux/kernel/git/gregkh/driver-2.6.git/

Both of these patches have been in the -next and -mm trees for a while.

The patch will be sent as a follow-on to this message to lkml for people
to see.

thanks,

greg k-h

From: Kay Sievers <kay.sievers@vrfy.org>

Some devices, like md, may create partitions only at first access,
so allow root= to be set to a valid non-existant partition of an
existing disk. This applies only to non-initramfs root mounting.

This fixes a regression from 2.6.24 which did allow this to happen and
broke some users machines :(
