Oops, this patch causes a build error:

drivers/md/dm-exception-store.c:235: error: implicit declaration of function 'area_location'
drivers/md/dm-exception-store.c:241: error: 'area' undeclared (first use in this function)
drivers/md/dm-exception-store.c:241: error: (Each undeclared identifier is reported only once
drivers/md/dm-exception-store.c:241: error: for each function it appears in.)

I'll drop this one, and the follow-on dm-exception-store.c patch as
well, as that was the only reason this patch was added.

If you want to redo these two patches, and get them into the
2.6.27-stable tree, please do so and send them to stable@kernel.org.

thanks,
