Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://github.com/0day-ci/linux/commits/Andi-Kleen/ipv4-ping-Fix-__init-... commit 29b4127f91ac9e7e739e917f3ff5e11fa3080c02 Author: Andi Kleen <ak(a)linux.intel.com&gt; AuthorDate: Fri Mar 29 17:46:00 2019 -0700 Commit: 0day robot <lkp(a)intel.com&gt; CommitDate: Sat Mar 30 19:08:17 2019 +0800 ipv4 ping: Fix __init* attributes ping_v4_net_ops references init functions, so needs to be __initdata. ping_proc_exit is then referenced from __initdata, so also needs to be __init.
