This is about deferred file locks from NFS, not gfs2's "deferred" lock mode.

So AFAIK we can't remove THAT without a certain amount of pain. Steve is on vacation / holiday this week, but he will be back on Thursday and Friday (which is a holiday). I'm all for getting rid of useless parameters, and I've done so on several occasions in GFS2.

Anything that simplifies the file locking interfaces is a good thing, particularly the deferred locking code. Fine with me.
