Kazuya Mio - June 24, 2013, 6:28 a.m.
According to mke2fs man, we can create a filesystem on the mounted device
when -FF option is specified.
However, currently we have to specify -F option third to force mke2fs.
This patch fixes the problem.

Oh, you mean we have to specify -F option three times ? It took me
some time to understand. Please rephrase the description.

Otherwise the patch looks good.

Thanks!
