Hi, I am writing this pseudo disk driver for FreeBSD and for write operations, I'd like to distinguish between newly allocated blocks versus overwritten blocks, because there are different actions I want to take for write operations involving newly allocated blocks and for write operations involving previously written blocks. Is it possible to make this distinction in the strategy routine? I'm not sure if my question is clear, so I could give more details. Thanks.
