+Subject: [PATCH 343/347] rt: PREEMPT_RT safety net for backported patches
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.tar.xz
+
+While doing some 4.19-rt cleanup work, I stumbled across the fact that parts of
+two backported patches were dependent on CONFIG_PREEMPT_RT, rather than
+the CONFIG_PREEMPT_RT_FULL used in 4.19 and earlier RT series.  The commits
+in the linux-stable-rt v4.19-rt branch are:
+
+dad4c6a33bf4e mm: slub: Don't resize the location tracking cache on PREEMPT_RT
+e626b6f873f2c net: Treat __napi_schedule_irqoff() as __napi_schedule() on PREEMPT_RT
+
+Discussing this at the Stable RT maintainers meeting, Steven Rostedt suggested that
+we automagically select CONFIG_PREEMPT_RT if CONFIG_PREEMPT_RT_FULL is on, giving
+us a safety net for any subsequently backported patches. Here's my first cut at
+that patch.
+
+I suspect we'll need a similar patch for stable RT kernels < 4.19.
