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?
