What about those two (Kconfig) patches which is in your current
bfq-4.11.y patchset.

I'm not sure I fully understand the purpose of the two patches you
propose (in your following emails).  The first patch seems to move BFQ
config options to a different position in Kconfig.iosched, but the
position of those items should be irrelevant.  Am I missing something?
The second patch seems to have to do with configuration bits of bfq
for blk, yet such a bfq version is not available in mainline.

In any case, for possible new submissions, you should inline your
patches.  For complete instructions on submitting patches, have a look
at Documentation/process/submitting-patches

All my testings was done with your patchset against Linux v4.11.y.
You have the same kconfig/kbuild stuff in your 0001 patch [1], so :-)?
What you have in 0001 is missing in Linux v4.12-rc1.
Not sure if this is intended.

4.12-rc1 contains bfq for blk-mq, while the patch you mention is for
bfq for blk (never accepted in mainline).  Maybe you could get a
clearer idea by having a look at the commits that add bfq (for blk-mq)
in 4.12-rc1.

I recall, Markus pointed me to that difference between the BFQ implementations.
For testing purposes: You want people to test BFQ in Linux v4.12?

I will re-submit and add a "4.12" in the subject-line when I am at home.
