On the call Ted said it would be desirable to run xfstests for all of these
configurations.  Since xfstests already runs quite a number of smaller tests
like fsx, etc, this would definitely be a very good smoke test for the most
common configurations.

I added "-t" to the ext2/ext3/ext4 configs above, since without those options
the features enabled for the various filesystems will not be the same as they
are formatted by default.  For example, with the default "-t ext4" a number
of other features like "flex_bg", "uninit_bg", "huge_file", "dir_nlink" and
"extra_isize" are enabled, but they shouldn't be enabled for ext2/ext3.

Cheers, Andreas
