No updates, this issue is not as pressing as other things the ext4 development
team is currently working on ...

Use the ext4.base file from already attached to other bug #14286
http://bugzilla.kernel.org/attachment.cgi?id=23214

unzip the above file(s) 
ext4.319.img.tar.gz
ext4.base.tar.gz 

And download the fsfuzzer from site
http://www.risesecurity.org/files/fsfuzzer-0.7.3.tar.gz

Untar it
cd fsfuzzer-0.7.3
./configure
make

cp ext4.319.img to fsfuzzer-0.7.3/cfs
cp ext4.base to fsfuzzer-0.7.3/fs
and run the file named run_test in fsfuzzer-0.7.3
./run_test ext4 319

Check the dmesg.

Thanks!!
