BFS
Hi!

If anyone interested, I've fixed BFS patch for 3.2.11-hardened:
http://powerman.name/download/kernel/3.2-hardened-sched-bfs-416.patch

I've format it similar to original patch
http://ck.kolivas.org/patches/bfs/3.2.0/3.2-sched-bfs-416.patch
so they can be easily compared using vimdiff etc.


P.S. BFQ patch apply to 3.2.11-hardened without any changes.
