+Subject: [PATCH 7/8] drm/i915/guc: Consider also RCU depth in busy loop.
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.10/older/patches-6.10.2-rt14.tar.xz
+
+intel_guc_send_busy_loop() looks at in_atomic() and irqs_disabled() to
+decide if it should busy-spin while waiting or if it may sleep.
+Both checks will report false on PREEMPT_RT if sleeping spinlocks are
+acquired leading to RCU splats while the function sleeps.
+
+Check also if RCU has been disabled.
