--- Comment #1 from Konstantin Belousov <kib@FreeBSD.org> ---
The patch is wrong, of course.  It breaks calling conventions for
lf_advlockasync()
which is the implementation for all advlock vops (except fuse and partially
nfs).

You need to adopt fuse to the interface provided by VOP.  If there is missed
information at the VOP call time, describe what sort of info is lost.
