[LTP] [PATCH 2/3] stat04+lstat03: fix bad blocksize mkfs option for xfs

[Cyril Hrubis]

Hi!
> Not all filesystems use "-b 1024" to set its blocksize. XFS uses
> "-b size=1024", so this test fails as "unknown option -b 1024" on
> xfs.

				       You can just add "-b" here
				       instead of creating a variable.

	  The more common style is if (!strcmp(...))

Otherwise it looks good.
