Kent and Bart - thanks for the review.
I've added setting the pull-up/down flags in lineevent_create(). And
I have added sanity checks to make pull-up and pull-down flags
mutually exclusive and only valid when the line is an input.
I tried to use "git send-email" to reply to your message but it
doesn't work seem to have threaded correctly, despite using
"--in-reply-to"
I have only submitted kernel patches before when I was completing the
Eudyptula Challenge, so I wasn't sure how to best post a follow-up
patch to address review feedback. Maybe starting a new thread with v2
of the RFC?
thanks,
drew
