Thanks for the fix!

It had been on my list to checking to see if the ext4 kunit tests
would pass, since Jan had mentioned that he had done the work to make
sure the ext4 kunit test would compile, but he hadn't gotten around to
try run the kunit test.  Unfortunately, I hadn't gotten to it.

I *think* the ext4 kunit tests should have caught this as well; out of
curiosity, have you tried running the ext4 kunit tests either before
or after this patch?  If so, what were your findings?

Cheers,
