Subject: [PATCH RHEL6 4/4] ext4: Support for 64-bit quota format

Bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=546311

Description:
Add support for new 64-bit quota format. It is enough to add proper
mount options handling. The rest is done by the generic code.

Please disregard that email. I just made a "quilt mail" mistake.
