From 5a685cd94b21a88efa6be77169eddef525368034 Mon Sep 17 00:00:00 2001 From: Cong Wang Date: Tue, 23 Feb 2021 10:49:27 -0800 Subject: skmsg: Get rid of struct sk_psock_parser struct sk_psock_parser is embedded in sk_psock, it is unnecessary as skb verdict also uses ->saved_data_ready. We can simply fold these fields into sk_psock, and get rid of ->enabled.
