Author: rmacklem Date: Sat Apr 9 23:55:27 2011 New Revision: 220507 URL: http://svn.freebsd.org/changeset/base/220507 Log: Add a VOP_UNLOCK() for the directory, when that is not what VOP_LOOKUP() returned. This fixes a bug in the experimental NFS server for the case where VFS_VGET() fails returning EOPNOTSUPP in the ReaddirPlus RPC, forcing the use of VOP_LOOKUP() instead.
