From 0dad4087a86a2cbe177404dc73f18ada26a2c390 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 24 Jan 2022 12:24:54 -0800 Subject: tcp/dccp: get rid of inet_twsk_purge() Prior patches in the series made sure tw_timer_handler() can be fired after netns has been dismantled/freed. We no longer have to scan a potentially big TCP ehash table at netns dismantle. Signed-off-by: Eric Dumazet Signed-off-by: David S.
