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.
