X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e130af5dab2abbf01c5d92ec5ac05912cf3d9aa7;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [TCP]: Fix double adjustment of tp->{lost,left}_out in tcp_fragment(). There is an extra left_out/lost_out adjustment in tcp_fragment which means that the lost_out accounting is always wrong. This patch removes that chunk of code.
