Hi Ted,
I don't know if you are aware of this, when running e2fsck on an ext4 filesystem
which was mounted with "journal_async_commit" option, the following error is
reported:
e2fsck 1.41-WIP (27-Apr-2008)
Ext3 journal superblock has an unknown incompatible feature flag set.
Abort<y>?
Seen with e2fsck from the latest next branch (1.41-WIP)

Support for the async journal flag is in the pu branch. See recent
discussions on the linux-ext4 list. There is some disagreement about
what is the right way to handle checksum failures, and what is
currently in the kernel is definitely buggy.
