I pulled them in to my testing stack yesterday afternoon.  There's a
good chance I'll end up delaying commiting these to the next merge
window, simply because I don't have the bandwidth at this point to
process any more significant changes to the for-next tree.  I think
it's much more important right now to get the rmap/reflink in the
the 4.6 merge window than these writeback changes.

Cheers,

Dave.
