Subject: [PATCH 5/6] locks: break delegations on any attribute modification
Date: Fri, 3 Feb 2012 16:09:56 -0500 [thread overview]
Message-ID: <1328303397-3872-6-git-send-email-bfields@redhat.com> (raw)
In-Reply-To: <20120203205818.GE2999@fieldses.org>
From: "J. Bruce Fields" <bfields@redhat.com>
NFSv4 uses leases to guarantee that clients can cache metadata as well
as data.
This covers chmod, chown, etc.
