From: Catalin Marinas Date: Sun, 27 Nov 2011 21:43:10 +0000 (+0000) Subject: sched/arch: Introduce the finish_arch_post_lock_switch() scheduler callback X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=01f23e1630d944f7085cd8fd5793e31ea91c03d8;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git sched/arch: Introduce the finish_arch_post_lock_switch() scheduler callback This callback is called by the scheduler after rq->lock has been released and interrupts enabled. It will be used in subsequent patches on the ARM architecture.
