Subject: [NETFILTER]: xt_time should not assume CONFIG_KTIME_SCALAR
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=53756524e42a71011f5ae6410d6ac386bf3a9e7b;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[NETFILTER]: xt_time should not assume CONFIG_KTIME_SCALAR

It is not correct to assume one can get nsec from a ktime directly by
using .tv64 field.
