Subject: fsfuzzer: exabyte file sizes
I'm messing with fsfuzzer and it created a filesystem with a huge
exabyte file which is larger than ext4 supports.
root@...on:/tmp# mount -o loop ext4_exabyte_file.img mnt/
root@...on:/tmp# ls -l mnt/
ls: cannot access mnt/config.h: Input/output error
ls: cannot access mnt/configure: Input/output error

I've uploaded the corrupted filesystem image to:
http://smatch.sf.net/upload/ext4_exabyte_file.img
Not a huge deal, but I thought I'd report it anyway.

dan carpenter
