Change to that rule or from? I *think* you just said:
- If ->writepage successfully starts writeout on the page it clears the dirty bit and returns 0
- If not successful, ->writepage unlocks the page and return 1
Who is going to be responsible for checking that the page dirty bit was really set, and what will happen if it wasn't?
