He means you've used u64 in a header without actually including any file
that defines the typedef. Linux header files aren't supposed to depend
on include order. They're supposed to stand alone. The point is that
if I include just #include osd_initiator.h into an empty kernel file
it's not supposed to spit undefined errors.

Right at the moment the u64 probably works because blkdev.h #includes
the file which defines it, but you're not supposed to rely on that.
