The last thing seen in the client test_log is

Unfortunately, there’s not much else in the console logs.
There are similar crashes with similar call traces, but have ll_dir_get_parent_fid() errors before the crash; https://testing.whamcloud.com/test_sets/5a91cd96-e21f-11e8-b67f-52540065bddc . So, it’s not clear is this is the same issue or not.
