Well, I just read the last link, and one of the paragraphs says 

"[softupdate] is still under a special license which prevents it from
being enabled by default, however it will eventually be switched to the
BSD license. (...) soft updates can be enabled for each filesystem
simply by tunefs -n enable fs (OpenBSD: tunefs -s enable)."

I wonder if OpenBSD 2.8 and above have softupdates enabled on default
install. I tried the above command, and all I got was this message

"tunefs: cannot open /dev/wd0a: Device busy"

For the record, although I doubt this will change much...

The filesystem in use in all BSD variants is the Fast File System.  FFS.
You can read all about it in many papers published over the years.  Read
the following:

And now, finally, for all the linux people, try this out:
