Ok, fortunately I've reproduced it on a different PC.  block/Makefile
was flawed, but, for unknown (to me) reasons, my system was perfectly
happy with the flaw.

I have downloaded the offending tree directly from the github page.

Here are my steps in super detail.

I followed the url:
https://github.com/0day-ci/linux/commits/Paolo-Valente/block-bfq-introduce-the-BFQ-v0-I-O-scheduler-as-an-extra-scheduler/20170402-100622
and downloaded the tree ("Browse the repository at this point in
history" link on the top commit, then "Download ZIP"), plus the
.config.gz attached to the email.

Then I built with no error.

To try to help understand where the mistake is, the compilation of the
files of course fails because each of the offending files does not
contain the definition of the reported functions.  But that definition
is contained in one of the other files for the same module.  I mean
one of the files listed in the following rule in block/Makefile:
obj-$(CONFIG_IOSCHED_BFQ)   += bfq-iosched.o bfq-wf2q.o bfq-cgroup.o

Maybe I'm making some mistake in the Makefile, or I forgot to modify
some other configuration file?

Help! :)

Paolo

I have downloaded the offending tree directly from the github page.

Here are my steps in super detail.

I followed the url:
https://github.com/0day-ci/linux/commits/Paolo-Valente/block-bfq-introduce-the-BFQ-v0-I-O-scheduler-as-an-extra-scheduler/20170402-100622
and downloaded the tree ("Browse the repository at this point in
history" link on the top commit, then "Download ZIP"), plus the
.config.gz attached to the email.

Then I built with no error.

To try to help understand where the mistake is, the compilation of the
files of course fails because each of the offending files does not
contain the definition of the reported functions.  But that definition
is contained in one of the other files for the same module.  I mean
one of the files listed in the following rule in block/Makefile:
obj-$(CONFIG_IOSCHED_BFQ)   += bfq-iosched.o bfq-wf2q.o bfq-cgroup.o

Maybe I'm making some mistake in the Makefile, or I forgot to modify
some other configuration file?

Help! :)

Hmm, this error is reproducible in 0day side, and you patches were applied on
