Hi Linus,

Please pull overlayfs updates for 6.12.

This branch has been sitting in linux-next for over a week and
it has gone through the usual overlayfs test routines.

The branch merges cleanly with master branch of the moment.

Thanks,
Amir.

overlayfs updates for 6.12

- Increase robustness of overlayfs to crashes in the case of underlying
  filesystems that to not guarantee metadata ordering to persistent storage
  (problem was reported with ubifs).

- Deny mount inside container with features that require root privileges
  to work properly, instead of failing operations later.

- Some clarifications to overlayfs documentation.
