Possible bug in open_by_handle

["William L. Jones" <jones@xxxxxxxxxxxxxxxxxx>]

In xfs_ioctl.c in open_by_handle fill_name_hash is call with  len:

        /*
         * Obtain/create a 'dentry'.
         */
        sqstr.name = sname;
        sqstr.len  = 2 * hlen;
        sqstr.hash = full_name_hash(sname, hlen);
                                            ^^^^

shouldn't  be 2 * len:

        /*
         * Obtain/create a 'dentry'.
         */
        sqstr.name = sname;
        sqstr.len  = 2 * hlen;
        sqstr.hash = full_name_hash(sname, 2 * len);
                                            ^^^^^^^
