[RFC PATCH v2 37/41] ovl: allow UUID and GUID owners when the upper layer does

[sashiko-bot at kernel.org]

> Changes to an overlay land in its upper layer, so whether the overlay
> can store UUID and GUID owners is the upper layer's business: take
> SB_I_UID_R over from it. Copy-up of such an owner from a lower layer
> into an upper layer without the flag keeps failing with -EOVERFLOW.
> 
> This is what a live system with a tmpfs over a read-only image needs
> to give files to UUID and GUID users.
