Merge tag 'ovl-fixes-7.4-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/overlayfs/vfs

Pull overlayfs fixes from Amir Goldstein:

 - Fixes for data-only layers (composefs), some for regressions from
   v6.16, which relaxed the requirements for redirects to data-only
   layers

 - Fix a use-after-free in lookup of a hardlink with a FUSE upper,
   reported by Sashiko

 - Fix a mount failure right after unmount of an overlay with the same
   upperdir

 - Reject lower layers on the same fs with different idmaps, which could
   decode file handles through the wrong layer

 - Minor fixes for a memory leak, an error message and readdir d_ino
