Well, at some point a few people like Alan Cox and Arjan VdV would like
to see this work on it's way to Linus's tree.

I'll do whatever is best and easiest for you and will bring a close to
my submission attempts.  I can also just go into the Kconfig where the
pti driver is configured and just make the selection bool, yes or no,
and not make it an option to compile this modularly.  Then I'll drop
this patch all together.  This is the whole reason why I'm making this
change.  I don't have to have the pti driver as a module, just more
convenient.  And within the fs/exec.c it states reads to 'current->comm'
without a lock is safe.
