Description bwcknr 2014-10-30 22:25:14 UTC 
As described in summary:

# equery f gentoo-sources | grep bfq
/usr/src/linux-3.17.2-gentoo/b/block/bfq-cgroup.c
/usr/src/linux-3.17.2-gentoo/b/block/bfq-ioc.c
/usr/src/linux-3.17.2-gentoo/b/block/bfq-iosched.c
/usr/src/linux-3.17.2-gentoo/b/block/bfq-sched.c
/usr/src/linux-3.17.2-gentoo/b/block/bfq.h

This makes kernel builds fail with:
No rule to make target block/bfq-iosched.o

Reproducible: Always

Steps to Reproduce:
1. merge gentoo-sources-3.17.2 with USE="experimental"
2. try to build kernel with bfq enabled
Actual Results:  
kernel should build fine

Expected Results:  
kernel build rails

I fixed this, but it may take a few hours to sync to your system.

The fixed 3.17.2 ebuild has K_GENPATCHES_VER="5" in it.

you can edit your own if you like and then do

ebuild gentoo-sources-3.17.2.ebuild manifest

and then emerge it.
