[PATCH 0/8] md: Make raid0 use sector-based quantities

This series of patches against Neil's for-next branch converts the
internal representations of block-based quantities in the raid0 code
to sector-based quantities.

There's also one trivial patch in this series, #6, which adds
KERN_INFO/KERN_ERR to a couple of printk's.

checkpatch.pl is happy with all eight patches, and the patched kernel
passes the raid0 tests of mdadm's test suite on my i386 UP box.

Please review.
