Subject: [PATCH 314/323] locking/rtmutex: switch to EXPORT_SYMBOL() for
 ww_mutex_lock{,_interruptible}()
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz

We can use EXPORT_SYMBOL() instead of EXPORT_SYMBOL_GPL() in
ww_mutex_lock_interruptible() and ww_mutex_lock(). That match
ww_mutex_unlock() well. And also good for 3rd kernel modules.
