[LU-7716] Do not do subdir check if source and target are in the same directory

Related — Thu, 4 Feb 2016 05:24:42 +0000

In mdt_reint_rename_internal(), we do not need do is_subdir check if source and target are in the same directory.

     
       /* Check if @mtgtdir is subdir of @mold, before locking child
         * to avoid reverse locking. */
        rc = mdt_is_subdir(info, mtgtdir, old_fid);  <--- no need check if mtgtdir == msrcdir
        if (rc)
                GOTO(out_put_old, rc);
