      Description

      sanity test_255c fails with 'Ladvise test 12, bad lock count, returned 1, actual 0'. It looks like this is only impacting Ubuntu 18.04 client testing.

      Looking at the client test_log from https://testing.whamcloud.com/test_sets/d1b23f66-fdd4-11e8-a97c-52540065bddc , a problem is that we can’t find lock_unused_count
