    signals: introduce kernel_sigaction() · b4e74264
    Oleg Nesterov 提交于
    Now that allow_signal() is really trivial we can unify it with
    disallow_signal().  Add the new helper, kernel_sigaction(), and
    reimplement allow_signal/disallow_signal as a trivial wrappers.
    
    This saves one EXPORT_SYMBOL() and the new helper can have more users.
