Ok so it seem like the problems you're seeing here after the revert might be cause wrong revert. Simply applying patches #1 through #14 on top of the c7788792a5e7b0d5d7f96d0766b4cb6112d47d75 (Linux 3.10-rc2 - that seem to be what is ext4 branch based on?) does not yield any errors without journal.

However I certainly hope it would not be necessary. I am still working to figure out what's going on. I'll keep you posted.
