    ftrace: freeze kprobe'd records · ecea656d

    Let records identified as being kprobe'd be marked as "frozen". The trouble
    with records which have a kprobe installed on their mcount call-site is
    that they don't get updated. So if such a function which is currently being
    traced gets its tracing disabled due to a new filter rule (or because it
    was added to the notrace list) then it won't be updated and continue being
    traced. This patch allows scanning of all frozen records during tracing to
    check if they should be traced.
