Date: Mon, 31 Aug 2026 21:35:28 +0000 [thread overview]
Message-ID: <20260831213528.B1D0F1F000E9@smtp.kernel.org> (raw)
In-Reply-To: <20260831-remove-pg_private-v2-2-3668159cd9e8@nvidia.com>
> A high-order AUX page sets PG_private on its first page and stores the
> order in first_page->private. Stop using PG_private and check
> first_page->private for AUX page order only in the ring buffer and its
> users. This is fine because page->private is 0 for order-0 AUX pages,
> matching the page order.
>
> It prepares for a future commit that remove PG_private.
