Subject: Subject: [PATCH] [PATCH] time: tick-sched: use bool for tick_stopped
Message-ID: <891d4f632fbff5052e11f2d0b6fac35d@codeaurora.org>
User-Agent: Roundcube Webmail/1.2.5

 From: John Zhao <yuankuiz@codeaurora.org>

Variable tick_stopped returned by tick_nohz_tick_stopped
can have only true / forse values. Since the return type
of the tick_nohz_tick_stopped is also bool, variable
tick_stopped nice to have data type as bool in place of int.
Moreover, the executed instructions cost could be minimal
without potiential data type conversion.
