Thanks for the interest.
I didn't post them online as the conference didn't provide it, and I
don't think the slides would be particularly interesting without the
prepared speech anyway.
The presentation described a simple prototype implementing a redirection
table on zone block devices. There was one bullet point explaining how a
generic kernel implementation would be an improvement. For zoned block
devices, an "append" like copy offload would be an even better option.
