    Subject[PATCH 4/7] pid: Export the symbols needed to use struct pid *
    Date
    pids aren't something that drivers should care about.
    However there are a lot of helper layers in the kernel that do
    care, and are built as modules. Before I can convert them
    to using struct pid instead of pid_t I need to export the
    appropriate symbols so they can continue to be built.
