Just grab Linus's tree, for instance. 4.18.3 does definitely not have support
for zoned null_blk, and null_blk_zoned.c should not exist. It was introduced
by this commit:
commit ca4b2a011948fae4e4d31490107db4926385a983
Author: Matias Bjørling <matias.bjorling@xxxxxxx>

null_blk: add zone support
which is not in 4.18. So either your sources are messed up, or something else
funky is going on at your end.
