When using a filter that rounds up to alignment boundaries, the tail bytes of the plugin are difficult to access correctly. Rather than duplicating lots of code already in the truncate filter, it's easier to just make the other filters default to rounding down and add doc links on how to round up instead.

I'm not sure exactly which version we're up to, but let's say it's version 4. I'm a lot happier with this version: - all filters have been reviewed and changed where I think that's necessary - can_extents is properly defined and implemented now - NBD protocol is followed - I believe it addresses all previous review points where possible The "only" thing
