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.
