  Modified files:
    sys/kern             vfs_lookup.c 
  Log:
   - Set cn_lkflags to LK_SHARED in the LOOKUP_SHARED case so that we only
     acquire shared locks on intermediate directories.
   - For the LASTCN, we may have to LK_UPGRADE the parent directory before
     we lookup the last component.
   - Acquire VFS_ROOT and dp locks based on the cn_lkflag.
