Looks like each maintainer may have his rule which may differ from the
rule laid down by Linus.

I have 2 network patches which went into 3.10-rc6, though these two bugs
are not regressions but has been there even before the git history.

On the other hand, 2 of my cgroup bug fixes were queued for 3.11 with
stable tag added.

And what about Documentation fixes and updates? Should those patches
also follow Linus' rule? I guess people have different opinions.
