* Updated ptlrpc_abort_reply() to not simply LBUG(). The current

    implementation has to poll for the SENT event at 1 second intervals, since
    the SENT callback cannot touch any state in the request.

*   Blindly wrapped all request flag updates in an IRQ spinlock (or just a
    spinlock if already at IRQ priority).  My head hurt too much trying to
    determine whether it was safe to update unlocked, and we know this is
    safe.  Maybe we should split out "owner" and "notifier" flag usage to
    separate words.
