I will probably try to come up with at least a proof of concept patch soon.
Once I have that much, I can start to think of what a VOP_WRITESAME()
might look like. If possible, it would be nice to get this in 15, since it would
have to wait for 16 otherwise.

Dan, if you could create a bugzilla PR (bugs.freebsd.org) asking for this as a
new feature, at least it won't get completely forgotten and I can hang patches
there.

You could look at the release schedule for FreeBSD 15 to see what the
optimistic bound on an implementation of this is.

ps: If you can discuss it, I would also like to hear something about the
      use case.  This can help justify the work.
