-Subject: [PATCH 05/10] drm/i915: Don't check for atomic context on PREEMPT_RT
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.9/older/patches-6.9-rt5.tar.xz
-
-The !in_atomic() check in _wait_for_atomic() triggers on PREEMPT_RT
-because the uncore::lock is a spinlock_t and does not disable
-preemption or interrupts.
-
-Changing the uncore:lock to a raw_spinlock_t doubles the worst case
-latency on an otherwise idle testbox during testing. Therefore I'm
-currently unsure about changing this.
