Subject: [UDP]: Move seq_ops from udp_iter_state to udp_seq_afinfo.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dda61925f84d89e2f2a4597d6298a05a2bc05c20;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[UDP]: Move seq_ops from udp_iter_state to udp_seq_afinfo.

No need to create seq_operations for each instance of 'netstat'.
