From 0fa2f5cb2b0ecd8d56baa51f35f09aab234eb0bf Mon Sep 17 00:00:00 2001 From: Konstantin Khlebnikov Date: Wed, 15 Jul 2015 12:52:01 +0300 Subject: sched/preempt, xen: Use need_resched() instead of should_resched() This code is used only when CONFIG_PREEMPT=n and only in non-atomic context: xen_in_preemptible_hcall is set only in privcmd_ioctl_hypercall(). Thus preempt_count is zero and should_resched() is equal to need_resched().
