From 17c916e321300d28f52ad6b195cad88be48e8421 Mon Sep 17 00:00:00 2001
From: Jeff Roberson <jeff@FreeBSD.org>

Subject: [PATCH]  - Mark the VOPs that require exclusive locks.  Those that
 aren't marked    with E may be called with a shared lock held.  This list
 really could    be made per filesystem if we had any filesystems which
 differed from    ffs in locking guarantees.  VFS itself is not sensitive to
 this except    where vgone() etc. are concerned.
