I agree that having better self-testing for sanity check features
would be a good thing to add, so that as we make changes in the
future, it's much more likely that we will find potential problems
sooner rather than later.
Given that amount of testing that we've done looking for regressions,
I'm feeling pretty good about the stability of the ext4 tree, so I'm
ready to send a pull request to Linus with the extent status tree.
Yes, we do have the problem with the defrag ioctl, but I trust that
Zheng will have a fix for us before v3.9 releases. Worst case, we can
just flush the extent status tree entirely which should
(inefficiently) solve the defrag bug.
Cheers,
