Author: rmacklem Date: Wed Jul 22 14:32:28 2009 New Revision: 195819 URL: http://svn.freebsd.org/changeset/base/195819 Log: When using an NFSv4 mount in the experimental nfs client with delegations being issued from the server, there was a case where an Open issued locally based on the delegation would be released before the associated vnode became inactive. If the delegation was recalled after the open was released, an Open against the server would not have been acquired and subsequent I/O operations would need to use the special stateid of all zeros. This patch fixes that case.
