From 15a1057c462f8248c4ae80ec2d70b60b19c5700e Mon Sep 17 00:00:00 2001
From: Eivind Eklund <eivind@FreeBSD.org>
Date: Wed, 20 Jan 1999 14:49:12 +0000
Subject: Add 'options DEBUG_LOCKS', which stores extra information in struct
 lock, and add some macros and function parameters to make sure that the
 information get to the point where it can be put in the lock structure.

While I'm here, add DEBUG_VFS_LOCKS to LINT.
