  SVN rev 188407 on 2009-02-09 20:50:23Z by jhb
  
  Mark udf(4) MPSAFE and add support for shared vnode locks during pathname
  lookups:
  - Honor the caller's locking flags in udf_root() and udf_vget().
  - Set VV_ROOT for the root vnode in udf_vget() instead of only doing it in
    udf_root().
  - Honor the requested locking flags during pathname lookups in udf_lookup().
  - Release the buffer holding the directory data before looking up the vnode
    for a given file to avoid a LOR between the "udf" vnode locks and
    "bufwait".
  - Use vn_vget_ino() to handle ".." lookups.
  - Special case "." lookups instead of calling udf_vget().  We have to do
    extra checking for the vnode lock for "." lookups.
