Announcing the latest release of the -ck patchset for improved responsiveness
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.)
A note about CPU scheduler cgroups - BFS does not support any of the cgroup
features but does implement a basic stub for the primary "CPU controller"
cgroup which creates the relevant cgroup filesystem but using it does nothing.
The reason for implementing this was that some applications now refuse to work
without it though they'll happily work with these stubs, even if they don't do
