The only conceivable reason for passing the mode as a separate parameter is - To change the mode dynamically at run time. - To share common code when the sequence is long and mostly shared between the various modes (as in open(2) or ll_rw_block()). I sincerely hope neither of those apply in this case. On the downside, it's more typing and uglier than a series of frob_bit_nonatomic() (probably temporarily or permanently aliased to frob_bit()) frob_bit_atomic() frob_bit_acquire() frob_bit_release() frob_bit_barrier() functions, and those also prevent you from doing something silly like frob_bit(x, y, O_DIRECT). Also, the MODE_ prefix might be wanted by something else. - : send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
