There are some other references to remove:

app/test/autotest_test_funcs.py:    child.sendline("set_watermark test 100")
app/test/autotest_test_funcs.py:    index = child.expect(["  watermark=100",
app/test/autotest_test_funcs.py:        return -1, "Fail [Bad watermark]"

doc/guides/prog_guide/ring_lib.rst:Water Marking
doc/guides/prog_guide/ring_lib.rst:The ring can have a high water mark (threshold).
doc/guides/prog_guide/ring_lib.rst:Once an enqueue operation reaches the high water mark, the producer is notified, if the water mark is configured.
