A bunch of your patches are obsoleted by > Al's security changes there. 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. Eric
