> Passing mmap(2) a 0 length doesn't make much sense anyway - for
example, Linux returns EINVAL.
Yup, but passing mmap(2) a zero-sized file and a non-zero length works just fine.

> Why do you want a mmap? Why not using a file?
Because Xen requires me to mmap it. Anyway, you're right, the use-case is too uncommon.
