Kernel tests

[Xiao Jia]

Why some of them are DISABLED?

And do we need to fix those FAILED user tests?

The disabled ones are ones that we haven't bothered to port properly
(they were originally written to just run by hand so don't conform to
the correct style dictated by the test suite). They will always fail.

Those user tests tend to fail in qemu because they are based on tsc
times which qemu sometimes gets confused about. I've mucked with them
to get them to pass on qemu in the past, but not reliably. If you
have suggestions for how to make them more reliable, that would be
great.

A few reasons. Some were meant to be run manually from the monitor,
some trash the state of the OS, some might just be loud and always
succeed, some might not work anymore, etc.

Probably.

IIRC, this one is racy, but no one has gotten around to fixing it.

This one fails because the VFS doesn't support openat.

Or maybe this is the racy one. Or maybe both.
