I should qualify that.  The thing completes and doesn't hang, but I get 6
failures:

    Failures: generic/604 generic/633 generic/645 generic/696 generic/697 generic/732

Though these don't appear to be anything to do with netfslib (see attached).
There are two cases where the mount is busy and the rest seems to be due to
id-mapped mounts and/or user namespaces.

The xfstest local.config file looks something like:

    export FSTYP=ceph
    export TEST_DEV=<ipaddr>:/test
    export TEST_DIR=/xfstest.test
    TEST_FS_MOUNT_OPTS='-o name=admin,mds_namespace=test,fs=test,fsc'
    export SCRATCH_DEV=<ipaddr>:/scratch
    export SCRATCH_MNT=/xfstest.scratch
    export MOUNT_OPTIONS='-o name=admin,mds_namespace=scratch,fs=scratch,fsc=scratch'
