  13     Run locktests, from the xfstests suite, on the given
  14     clients. Whether the clients are ceph-fuse or kernel does not
  15     matter, and the two clients can refer to the same mount.
  16
  17     The config is a list of two clients to run the locktest on. The
  18     first client will be the host.
  19
  20     For example:
  21        tasks:
  22        - ceph:
  23        - ceph-fuse: [client.0, client.1]
  24        - locktest:
