+From 740bc44f8756ed7c76a697de3eb3eae130c2de77 Mon Sep 17 00:00:00 2001

+Subject: [PATCH 165/323] lockdep: Reduce header files in debug_locks.h
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz
+
+The inclusion of printk.h leads to circular dependency if spinlock_t is
+based on rt_mutex.
+
+Include only atomic.h (xchg()) and cache.h (__read_mostly).
+
