yes and no ... EINVAL is returned if the specific clock is not implemented,=
=20
but the problem is that EINVAL is used for more than just the clock type;=20
it's also used for checking the parameters given to it ... so if you were t=
o=20
call the kernel with a clock that is implemented but with bogus parameters,=
=20
you'd get back EINVAL

or, if the kernel itself had a broken check and it returned EINVAL when it=
=20
should not have, you'd get a bogus PASS with your proposed changes

timer_create() is a POSIX function with a defined interface ... if linux do=
es=20
not conform to that interface (regardless of the reason), it is a test=20
failure ... the fact linux has not yet implemented said features does not=20
matter
