http://phk.freebsd.dk/misc/b_iocmd.patch
B_WRITE is bogusly defined as zero, which is a perfect candidate
for coding and logic mistakes, we saw the most recent victim of
this bogosity as recently as a few days ago.
This patch moves the "io-command" aspect of the b_flags into a new
struct buf field called b_iocmd.
This patch is the first step towards the stackable BIO system as
sketched out on http://www.freebsd.org/~phk/Geom/
Please test & review.
