Function Documentation

static atomic_count_t atomic_add	(	atomic_t *	val,
		atomic_count_t	i
	)			[inline, static]

Atomic add operation.

Use atomic compare and swap operation to atomically add signed value.

Parameters:

	val	Atomic variable.
	i	Signed value to be added.

Returns:

Value of the atomic variable as it existed before addition.
