It seems complicated, but with the screen template, it's almost habit.
I don't even have to think about it. 

I tried the bfs patch on rc4 of the 4.0 kernel, but it got these errors:

kernel/sched/bfs.c:4811:50: error: redefinition of ‘io_schedule’

I'm currently running a compile on a vanilla 3.19 with the bfs and bfq
patches applied.  If it doesn't have these errors, I can see if I get
the same behavior as you when compiling.
