This patch differs from the RHEL5 fix (Red Hat bz #555754) which simply writes to the 8-byte value field of the quota. In upstream quota code, we're required to write the entire quota (88 bytes) which can be split across a page boundary. We check for such quotas, and read/write the two parts from/to the corresponding pages holding these parts. With this patch, I don't see the bug anymore using the reproducer in Red Hat bz 555754. I successfully ran a couple of simple tests/mounts/ umounts and it doesn't seem like this patch breaks anything else.
