Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://github.com/0day-ci/linux/commits/Florian-Westphal/test_rhashtable...
commit c1bd3689a70d1ba1a2f7c6781770920087166018
Author: Florian Westphal <fw(a)strlen.de>
AuthorDate: Mon Sep 18 23:07:11 2017 +0200

CommitDate: Tue Sep 19 13:55:51 2017 +0800
test_rhashtable: add test case for rhl_table interface
also test rhltable. rhltable remove operations are slow as
deletions require a list walk, thus test with 1/16th of the given
entry count number to get a run duration similar to rhashtable one.
