[patch V3 24/64] locking/rtmutex: Prevent future include recursion hell
From: Thomas Gleixner
Date: Thu Aug 05 2021 - 11:43:15 EST
From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx>
rtmutex only needs raw_spinlock_t, but it includes spinlock_types.h which
is not a problem on an non RT enabled kernel.
RT kernels substitute regular spinlocks with 'sleeping' spinlocks which
are based on rtmutexes and therefore must be able to include rtmutex.h.
Include spinlock_types_raw.h instead.
