Bug found in ext3 quota enabled fs

Bug found in ext3 quota enabled fs

[Ralf Nyren]

Greetings,

I did an rsync of a remote file to a local ext3 filesystem with journaled
quotas enabled. Got the kernel BUG report below... I was able to reproduce
the error. Let me know if there is any additional info that would help.

Best regards, Ralf
