Subject: [TCP]: Kill bogus comment above tcp_tso_acked().
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a56476962e92a6c389a1a561274d4a27607b7b5f;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[TCP]: Kill bogus comment above tcp_tso_acked().

Everything stated there is out of data.  tcp_trim_skb()
does adjust the available socket send buffer space and
skb->truesize now.
