SPIN_LOCK_UNLOCKED and RW_LOCK_UNLOCKED are deprecated. These interfere
with lockdep state tracking.
Most of the time, you can simply turn:
static spinlock_t xxx_lock = SPIN_LOCK_UNLOCKED;
into:
static DEFINE_SPINLOCK(xxx_lock);
Static structure member variables go from:
struct foo bar {
.lock = SPIN_LOCK_UNLOCKED;
};
to:
struct foo bar {
.lock = __SPIN_LOCK_UNLOCKED(bar.lock);
};
Declaration of static rw_locks undergo a similar transformation.
