Hi Jens,

this series removes the revalidate_disk() function, which has been a
really odd duck in the last years. The prime reason why most people
use it is because it propagates a size change from the gendisk to
the block_device structure. But it also calls into the rather ill
defined ->revalidate_disk method which is rather useless for the
callers. So this adds a new helper to just propagate the size, and
cleans up all kinds of mess around this area. Follow on patches
will eventuall kill of ->revalidate_disk entirely, but ther are a lot
more patches needed for that.
