    Subject[RFC][PATCH 3/6] selftests/ftrace: Have reset_ftrace_filter handle modules
    From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

    If a function probe in set_ftrace_filter belongs to a module, it will
    contain the module name. Like:

    wmi_query_block [wmi]:traceoff:unlimited

    But writing:

    '!wmi_query_block [wmi]:traceoff' > set_ftrace_filter

    will cause an error. We still need to write:

    '!wmi_query_block:traceoff' > set_ftrace_filter
