NAME
     VOP_LEASE — validate a vnode for a particular set of credentials and
     operation type

SYNOPSIS
     #include <sys/param.h>
     #include <sys/mount.h>

     int
     VOP_LEASE(struct vnode *vp, struct proc *p, struct ucred *cred,
	 int type);

DESCRIPTION
     This entry point is currently not implemented.  I believe the idea is to
     validate a vnode for a particular set of user credentials and operation
     type.  The two operation types supported are LEASE_READ and LEASE_WRITE.
     The function currently always returns 0.

LOCKS
     The vnode must be exclusively locked on entry, and should remain exclu‐
     sively locked on return.

RETURN VALUES
     If successful, zero is returned.  Otherwise, well... zero is returned
     too.

SEE ALSO
     VOP_READ(9), VOP_WRITE(9)
