[PATCH] xfs/191: skip tests on older xfsprogs

[Xiao Yang]

From: root <root@localhost.localdomain>

If we don't have /tmp/foo file on xfsprogs 3.2.2, _require_xfs_mkfs_validation
will fail because mkfs.xfs can't create this file.  We need to skip tests
before xfsprogs 4.7.0, so fix it.  the feature has been introduced since
xfsprogs 4.2.0:

I think the file can be touched unconditionally.

Thanks,

If the file already exists and mtime/atime of the file is important,
then it could be an issue. It looks improbable, but still, maybe we
should be on the safe side?

Anyway, thanks for spotting this.

Couple of things here:

	1. this is an xfs specific check. The function needs to have
	   "xfs" in it's name. i.e. _xfs_mkfs_validation_check

	2. Don't hard code temporary files ie use mktemp for
	   creating the file like so:

		imgfile=`mktemp`
		.....
		rm -f $imgfile

	3. mkfs.xfs takes human readable units for sizes, such as
	   "1g" for a 1GB filesystem and "260k" for the log size. No
	   need calculations in the script for this, and this gets
	   rid of overly long lines and makes it easier to read.

	4. Whitespace between each check and result processing makes
	   it much easier to see each of the operations being
	   performed during the check.

i.e.

_xfs_mkfs_validation_check()
{
	local imgfile=`mktemp`
	local cmd="$MKFS_XFS_PROG -f -N -d file,name=/tmp/foo,size=1g"

	$cmd -s size=2s >/dev/null 2>&1
	local sum=$?

	$cmd -l version=2,su=260k >/dev/null 2>&1
	sum=`expr $sum + $?`

	rm -f $imgfile
	return $sum
}

Cheers,

Dave.
