Thanks for this.
One nit...
The options and semantics proposed for a new zfs dataset property:
sync=default
This is the default option. Synchronous file system transactions
(fsync, O_DSYNC, O_SYNC, etc) are written out (to the intent log)
and then secondly all devices written are flushed to ensure
the data is stable (not cached by device controllers).
The naming of this one seems strange.
I would have had something like sync=posix, and document that sync=posix
is the default. (Maybe posix isn't the right term.) sync=default doesn't
actually tell you what the behavior is.
