Subject: xen/preempt: use need_resched() instead of should_resched()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a7da51ae10032a507ddeae6a490916eadbd1e10a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

xen/preempt: 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().
