From: Ursula Braun Date: Fri, 3 Aug 2018 08:38:33 +0000 (+0200) Subject: net/smc: no cursor update send in state SMC_INIT X-Git-Tag: v5.15~8329^2~2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5607016cd1bbec538050b495669c3c8c5a2cee80;p=platform%2Fkernel%2Flinux-starfive.git net/smc: no cursor update send in state SMC_INIT If a writer blocked condition is received without data, the current consumer cursor is immediately sent. Servers could already receive this condition in state SMC_INIT without finished tx-setup. This patch avoids sending a consumer cursor update in this case.
