+Subject: [PATCH] prinkt/nbcon: Add a scheduling point to nbcon_kthread_func().
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.10/older/patches-6.10.2-rt14.tar.xz
+
+Constant printing can lead to a CPU hog in nbcon_kthread_func(). The
+context is preemptible but on !PREEMPT kernels there is no explicit
+preemption point which leads softlockup warnings.
+
+Add an explicit preemption point in nbcon_kthread_func().
