From: Alexander Gordeev Date: Wed, 21 Mar 2012 16:22:35 +0000 (+0100) Subject: genirq: Get rid of unneeded force parameter in irq_finalize_oneshot() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f3f79e38d51f8a419f4c484a86ece4baea35b993;p=linux-beck.git genirq: Get rid of unneeded force parameter in irq_finalize_oneshot() The only place irq_finalize_oneshot() is called with force parameter set is the threaded handler error exit path. But IRQTF_RUNTHREAD is dropped at this point and irq_wake_thread() is not going to set it again, since PF_EXITING is set for this thread already. So irq_finalize_oneshot() will drop the threads bit in threads_oneshot anyway and hence the force parameter is superfluous.
