From: Matthieu Baerts Date: Thu, 9 Mar 2023 14:50:03 +0000 (+0100) Subject: mptcp: avoid setting TCP_CLOSE state twice X-Git-Tag: v6.6.17~5289^2~44^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3ba14528684f528566fb7d956bfbfb958b591d86;p=platform%2Fkernel%2Flinux-rpi.git mptcp: avoid setting TCP_CLOSE state twice tcp_set_state() is called from tcp_done() already. There is then no need to first set the state to TCP_CLOSE, then call tcp_done().
