Subject: [NETNS]: Add netns parameter to fib_select_default.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=010278ec4cdf404aefc0bbd5e7406674fec95286;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[NETNS]: Add netns parameter to fib_select_default.

Currently fib_select_default calls fib_get_table() with the
init_net. Prepare it to provide a correct namespace to lookup default
route.
