The -F flag to xfs_io originally enabled it to operate on non-xfs filesystems. This restriction was removed upstream in favor of gracefully failing on the handful of operations that actually required xfs, and the option was deprecated. However, xfstests is still used on distros with older xfsprogs, and so "xfs_io -F" was necessary throughout xfstests. Simplify this by appending -F to XFS_IO_PROG when it's needed - i.e. if we're using old xfsprogs on a non-xfs filesystem. This will eliminate errors when new tests leave out the -F, and if and when -F is finally removed, there will be one central location in xfstests to update.
