Maybe, but kmalloc() does not. 16-byte-alignment means an address like 0xyyyy0, the last digit zero. this is not returned by kmalloc(). I had the problem of aligned memory in conjunction with DMA scripts - I do also with the two-pointer-method. allocation one, advancing the second to an aligned address, use it, and then free the first pointer.
Best regards,
