Hey Doug,

I tried as you suggested... only that didn't help.  So I actually had to get down into the guts to figure out what was going wrong.

It turned out to be a bug in the block layer of the 3.18 kernel that required a one line change.  With that fixed, the FastWrite patch works like a charm.

Thanks!
