It's a little different, though similar. relayfs is an unstructured buffer. This would be a sequence of events with a common timestamp format, and hopefully other commonalties too.
I agree that the underlying buffer structure could be shared, as has been pointed out (buried in this long thread). However, in another buried comment, it was pointed out that relayfs would have no users once this was done, so ...
I don't think we can remove relayfs before adding this and switching over the users though (possibly it could all be done at the same time, but messy)
