This is normally just a branded version of BFS with some different default
kernel options, however this version incorporates Jens Axboe's writeback
throttling patch version 7 which in my testing made a dramatic improvement to
behaviour under heavy write loads (no benchmarks.)

Thanks for testing it, and I'm glad you found it effective and useful.
I'll make a renewed push to get it upstream soon, need to run a set of
performance benchmarks to ensure that it doesn't regress anything I'm
aware of.
