Running xfs/205 triggers the following error: ---------------------------------------------- QA output created by 205 +./tests/xfs/205: line 61: 098: value too great for base (error token is "098") ... ---------------------------------------------- If b2 variable is a 2-digit number beginning with 0(e.g. 098), it will be treated as octal vaule instaed of decimal value. We try to declare it as decimal value forcely. Signed-off-by: Xiao Yang <yangx.jy@cn.fujitsu.com> Reviewed-by: Eryu Guan <guaneryu@gmail.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
