[patch 21/50] locking/lockdep: Reduce includes in debug_locks.h
From: Thomas Gleixner
Date: Tue Jul 13 2021 - 12:13:58 EST
From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx>
The inclusion of printk.h leads to a circular dependency if spinlock_t is
based on rtmutexes on RT enabled kernels.
Include only atomic.h (xchg()) and cache.h (__read_mostly) which is all
what debug_locks.h requires.
