It would be a good idea to:
1) mention the subject of said path as no-one remember all these
SHA-1 anyway (but include the SHA-1 for reference.
2) copy the author of said patch.
The relevant patch is: "block: move stats from disk to part0"
I have copied Tejun and JEns.
The rest of the mail kept for reference.
