Before anything is merged definitely.

Al dealt with mount options from the LSMs in a slightly different way
than I did.  At a practical level Als version of the changes to the LSMs
and mine are you say po-tae-toe I say po-tah-toe differences so I don't
see that influencing semantics up at the api level.

For purposes of disucssing an API (not of merging one) I chose to start
with code I had a reasonable amount of testing against, so that other
people could play with it without expecting trouble.
