[PATCH 0/1] LP#309378 -- port dm-raid4-5 to 2.6.28 and re-enable

[Andy Whitcroft]

Someone seems to be using dm-raid4-5 and has filed a bug on it.  There
is no later version available upstream.  I have therefore attempted a
forward port of this.  The port seems trivial enough but raid is obviously
something rather sensitive as its failure mode is unpleasant.

The main thing is that an interface in the kernel was no longer used
by anything and was removed (a common occurance), so I have had to
reinstate this.  Basically all internal users of the locked form
of {set,clear}_page_locked() had gone so they were removed.  Now it
is entirly possible we could move to the unlocked interfaces, but it
is significantly safer to assume not and reinstate them; based on the
assumption that upstream will port this forward to 2.6.28 at some point
after release and is far better placed to make that call.

Comments?
