Hah!!!!

You merged a LSM hook that is only good for breaking chrome's sandbox,
over my expressed objections.  After I tested and verified that
is what it does.

I asked for testing. None was done.  It was claimed that no
security sensitive code would ever fail to check and deal with
all return codes, so no testing was necessary.  Then later a
whole bunch of security sensitive code that didn't was found.

The only redeeming grace has been that no-one ever actually uses
that misbegotten security hook.

P.S.  Sorry for this off topic rant but sheesh.   At least from
my perspective you deserve plenty of bashing.
