Subject: [PATCH net-next v1 08/13] skbuff: Call skb_zcopy_clear() before unref'ing fragments
Date: Tue, 5 Jan 2021 14:07:01 -0800 [thread overview]
Message-ID: <20210105220706.998374-9-jonathan.lemon@gmail.com> (raw)
In-Reply-To: <20210105220706.998374-1-jonathan.lemon@gmail.com>
From: Jonathan Lemon <bsd@fb.com>
RX zerocopy fragment pages which are not allocated from the
system page pool require special handling. Give the callback
in skb_zcopy_clear() a chance to process them first.
