28 * These are deprecated legacy interfaces for atomic and synchronization
29 * operations.
30 *
31 * Define OSATOMIC_USE_INLINED=1 to get inline implementations of the
32 * OSAtomic interfaces in terms of the <stdatomic.h> primitives.
33 *
34 * Define OSSPINLOCK_USE_INLINED=1 to get inline implementations of the
35 * OSSpinLock interfaces in terms of the <os/lock.h> primitives.
36 *
37 * These are intended as a transition convenience, direct use of those
38 * primitives should be preferred.
