Hi!

True, these are part of two different runtest files and both runtest
files are part of default scenario. I do not think that this is wrong as
it is.

It's rather limitation of the current system to run testcases. What I
would rather is is some label based system, where testcases can be
labeled with different scenarios.

I.e. in this cases move_pages would be labeled as syscalls, numa and
default. Then we can run testcases by labels rather than runtest
files...

Adding checks for missing functionality should be pretty
straightforward and patches are welcome :).

The runltp script contains code to create the $LTPROOT/output directory
so there are a few testcases that expect that directory to exist,
nevertheless they should create test temporary directory with tst_tmpdir
and use it instead.

We forget to rename the TCID after we renamed the file. Fixed.
