Thanks to some help Mingming Cao we now have support for extX with up to 
64k blocksize. There were several issues in the jbd layer.... (The ext2 
patch that Christoph complained about was dropped).

The patchset can be tested (assuming one has a current git tree)

git checkout -b largeblock
git pull git://git.kernel.org/pub/scm/linux/kernel/git/christoph/largeblocksize.git largeblock

... Fiddle around with large blocksize functionality....

git checkout master

... Back to Linus' tree.

git branch -D largeblock

... Get rid of it.
