Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ * procfs-based user access to generic RPC statistics. The stats files
+ * reside in /proc/net/rpc.
+ *
+ * The read routines assume that the buffer passed in is just big enough.
+ * If you implement an RPC service that has its own stats routine which
+ * appends the generic RPC stats, make sure you don't exceed the PAGE_SIZE
+ * limit.
