[PATCH 0/7] fstests: enable sparse checking & fix fallout

[Eric Sandeen <sandeen@xxxxxxxxxx>]

After the endian bug last week, hch asked whether we should enable
sparse checking in xfstests.

This does so, in the same manner as the kernel and xfsprogs,i.e.
make C=1 or make C=2.

The rest of the patches fix most of the warnings that showed up
for me after that.

Thanks,
-Eric
