Hi Jan,

Thank you for your reply.

I've changed the workload to perform appends rather than in-place updates.

Appending sufficient data will cause a new block to be allocated.

On fsync, this newly allocated data block will be written out and in ordered
mode,
the journal entry will contain the block bitmap (with the bit set for the newly
allocated block) and the inode table that maps the offset to this block.

In this particular case, if `data_err=abort` is enabled, the journal should
abort when it fails to write the newly allocated data block.

However, that doesn't seem to be the case. I've attached an updated TGZ
containing the append workload.

The bitmap has the block set, the inode table still points to the block, but
the block has not been overwritten with the intended data. It still contains
it's old contents.
