Subject: tcp: fix tcp_probe_timer() for TCP_USER_TIMEOUT
X-Git-Tag: v4.13-rc1~157^2~398
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=4ab688793e086ef6d1744a0f803fe9770a1ae5d0;p=uclinux-h8%2Flinux.git

tcp: fix tcp_probe_timer() for TCP_USER_TIMEOUT

TCP_USER_TIMEOUT is still converted to jiffies value in
icsk_user_timeout

So we need to make a conversion for the cases HZ != 1000

Fixes: 9a568de4818d ("tcp: switch TCP TS option (RFC 7323) to 1ms clock")
