Subject: [PATCH AUTOSEL 5.11 10/38] net: correct sk_acceptq_is_full()
From: liuyacan <yacanliu@....com>
[ Upstream commit f211ac154577ec9ccf07c15f18a6abf0d9bdb4ab ]
The "backlog" argument in listen() specifies
the maximom length of pending connections,
so the accept queue should be considered full
if there are exactly "backlog" elements.
