    LINUX 5.3.0: Use send_sig instead of force_sig
    Linux 5.3.0 commit 3cf5d076fb4d48979f382bc9452765bf8b79e740 "signal
    Remove task parameter from force_sig" (part of siginfo-linus branch)
    changes the parameters for the Linux kernel function force_sig. See LKML
    thread starting at
    According to the LKML discussion and the above commit message force_sig
    is only safe to deliver a synchronous signal to the current task. To
    send a signal to another task, we're supposed to use send_sig instead,
    which has been available since at least linux 2.6.12-rc12.
    Currently, rx_knet calls force_sig to kill the rxk_ListenerTask.  With
    the Linux 5.3.0 kernel, this module fails to compile due to the above
    noted changes.
    Replace the force_sig call with send_sig.  In order to use send_sig, the
    rxk_listener thread must allow SIGKILL and during shutdown (umount)
    SIGKILL must be unblocked for the rxk_listener thread.
    Note that SIGKILL is initially blocked on rxk_listener and is only
    unblocked when shutting down the thread.  Having the signal blocked is
    sufficient to prevent unwanted signals from reaching the rxk_listener
    thread during normal operation.
