[Impact]
An unprivileged user may cause unintended xattrs to be set on the upper
layer of overlayfs.

[Backport]
An upstream fix was sufficient to prevent this issue on focal.

[Potential regression]
overlayfs users using metacopy=on may regress.

Miklos Szeredi (1):
  ovl: adhere to the vfs_ vs. ovl_do_ conventions for xattrs
