While doing a bit of adding argument names to fs.h,
I looked at lm_grant and it seems the 2nd argument

This doesn't apply as it depends on some other patches
but it should be clear enough...

Fine with me. I'd be happy to remove all the deferred locking code from
dlm; it never really worked.

Hi,
GFS2 uses deferred locks, at the very least in its direct_io path
(gfs2_direct_IO in aops.c). 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.

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