[PATCH 03/16] signal: remove superflous try_to_freeze() loop in do_signal_stop()

From: Tejun Heo
Date: Mon Dec 06 2010 - 11:58:36 EST


do_signal_stop() is used only by get_signal_to_deliver() and after a
successful signal stop, it always calls try_to_freeze(), so the
try_to_freeze() loop around schedule() in do_signal_stop() is
superflous and confusing. Remove it.
