Hi all
A while ago Ilya pointer out that since commit 1cb039f3dc16 ("bdi:
replace BDI_CAP_STABLE_WRITES with a queue and a sb flag"), the stable
write flag on the queue wasn't used for writes to the block devices
nodes any more, and willy suggested fixing this by adding a stable write
flags on each address_space. This series implements this fix, and also
fixes the stable write flag when the XFS RT device requires it, but the
main device doesn't (which is probably more a theoretical than a
practical problem).
