Hmm, I agree, a simple make test would do wonders for linux,
something which goes through all the syscalls and stuff like that, making
sure everything returns sane values.
However, the real test of the kernel does come when linux is
running under a NORMAL_LOAD * 25 type of situation. That is something
that needs to take time. The question on the table is then, what type of
load do we want on the system, doing / thrashing / kicking the crap out of
what and for how long?
I'm not a kernel hacker (yet), so I can't answer these questions
as well as I'd want ...
