From: Stephen Hemminger Date: Sat, 28 Jun 2008 03:00:19 +0000 (-0700) Subject: tcp: /proc/net/tcp rto,ato values not scaled properly (v2) X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7be87351a1f6430426e88b4fcde353ab3330caff;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git tcp: /proc/net/tcp rto,ato values not scaled properly (v2) I found another case where we are sending information to userspace in the wrong HZ scale. This should have been fixed back in 2.5 :-( This means an ABI change but as it stands there is no way for an application like ss to get the right value.
