Re: [Cluster-devel] [PATCH] gfs2-utils: Add the beginnings of a test suite



Hi,

Looks good to me. Would also be nice to add a test which creates a
variety of different filesystems in a sparse file and then runs fsck
over them to check that they are clean. That should also be quite easy
to do,

Steve.
