If anyone has any objections, please let me know. ------------------ From: Sebastian Andrzej Siewior [ Upstream commit 007240d59c11f87ac4f6cfc6a1d116630b6b634c ] The macro __SPIN_LOCK_INITIALIZER() is implementation specific. Users that desire to initialize a spinlock in a struct must use __SPIN_LOCK_UNLOCKED(). Use __SPIN_LOCK_UNLOCKED() for the spinlock_t in imc_global_refc.
