Hi!
If I remember right it's POSIX requirement to return ENOMEM in this case
and EINVAL sometimes slips in into kernel arch specific memory
management code.
Citing POSIX:
[ENOMEM]
MAP_FIXED was specified, and the range [addr,addr+len) exceeds that
allowed for the address space of a process;
So if the testcase fails, it's a bug albeit a minor one.
What we should do depends on how strict we are. I would personaly change
the testcase to have specific failure message for EINVAL, ideally
pointing to this discussion on mailing list archive. But if all the rest
of you consider this minor enough to be ignored we can proceed with the
original patch as well.
