Hi Linus,

Please pull overlayfs fixes for 6.8-rc2.

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

The branch merges cleanly with master branch of the moment.

Thanks,
Amir.

  ovl: mark xwhiteouts directory with overlay.opaque='x' (2024-01-23 12:39:48 +0200)

----------------------------------------------------------------
overlayfs fixes for 6.8-rc2:

- Change in on-disk format for the new "xwhiteouts" feature introduced in v6.7

  The change reduces unneeded overhead of an extra getxattr per readdir.
  The only user of the "xwhiteout" feature is the external composefs tool,
  which has been updated to support the new on-disk format.

  This change is also designated for 6.7.y.
