Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is

commit c1bd3689a70d1ba1a2f7c6781770920087166018

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.
