@xuhdev: are all your recent changes to this stack just merges/rebases? I need to know if landing a prior version is safe.

also, can you stop merging/rebasing? I already checked that the failures weren't related to this diff, and we have some internal systems that will reject commits if the version we are trying to merge isn't up-to-date with the the PR. I'm not sure if the merges will go through now or I'll have to do redo it.

I realize we have no automated communication on this state so this is totally invisible to you, sorry about that!

[xuhdev]

@gchanan Yes, I just rebased this morning, in case there's any conflict. Sorry for the confusion!

[gchanan]

ok, I think it makes the most sense to punt on getting this into v1.2 -- mainly because we can't land anything right now.

[gchanan]

Also, no need to apologize -- thanks so much for your contributions, they are really great.

[xuhdev]

@gchanan No problem! Thanks for your review!
