Neil - can you describe for me (us all?) what is meant by intent�logging here. Well, I can guess - I suppose the driver marks the bitmap before a write (or group of writes) and unmarks it when they have completed successfully. Is that it? If so, how does it manage to mark what it is _going_ to do (without psychic powers) on the disk bitmap? Unmarking is easy - that needs a queue of things due to be unmarked in the bitmap, and a point in time at which they are all unmarked at once on disk. Then resync would only deal with the marked blocks.
