I think I meant "must not use" - and indeed memslots must *not* be mapped as shareable. I'll update to this wording: When this capability is enabled all memory in memslots must be mapped as not-shareable (no MAP_SHARED), attempts to create a memslot with MAP_SHARED will result in an -EINVAL return. > Otherwise: > > Reviewed-by: Catalin Marinas <catalin.mari...@arm.com> > Thanks, Steve
