This is actually something I wanted to ask you guys about.  There are
a series of ext4-specific tests that I could potentially add, but I
wasn't sure how welcome they would be in xfstests.  Assuming that
ext4-specific tests would be welcome, is there a number range for
these ext4-specific tests that I should use?

BTW, we have an extension to xfstests that we've been using inside
Google where Google-internal tests have a "g" prefix (i.e., g001,
g002, etc.).  That way we didn't need to worry about conflicts between
newly added upstream xfstests, and ones which were added internally.
Would it make sense to start using some kind of prefix such as "e001"
for ext2/3/4 specific tests?
