I was just going by current xfstests convention. i.e, in common/rc:

# Prints the md5 checksum of a given file
_md5_checksum()
{
        md5sum $1 | cut -d ' ' -f1
}

Which is used by all the hole punch tests and generic/311.

Make of that what you will, but I'd prefer to see consistency of
implementation across tests... ;)

Cheers,

Dave.
