Richard,

Maybe it's not my business to interfere with ubifs development and I
haven't seen your patch.

But on the face of it, it doesn't sound like fixing O_TMPFILE is a
trivial fix, so not sure
it is wise to send a patch for -rc7?...

How about sending the patch to disable O_TMPFILE for -rc7 and queuing
your fix for v4.12?
Without any patch, v4.11 is going to have a regression with overlayfs+ubifs.

Amir.
