Subject: [PATCH v2 net-next 2/4] skbuff: constify skb_propagate_pfmemalloc() "page" argument
Message-ID: <20210127201031.98544-3-alobakin@pm.me>
In-Reply-To: <20210127201031.98544-1-alobakin@pm.me>

MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: quoted-printable
Precedence: bulk

The function doesn't write anything to the page struct itself,
so this argument can be const.

Misc: align second argument to the brace while at it.
