Will do.

For tst_brk() these checks are removed in my patchset that changes how
TBROK is propagated, so that tst_brk() works with TFAIL and TPASS as
well.

We also had a discussion about removing TWARN since there is not a big
difference between TBROK and TWARN and replacing TWARN with
tst_res(TBROK, ...) as that would make things simpler. Currently there
is no good rule where to use TBROK and where TWARN so removing TWARN
sounds like a good option.

See above.

Yes, errno is not defined in shell.
