New USB ID 2001:3c25

[Larry Finger]

Scott,

I see that you added the USB ID in the subject for the DWA-130 device in commit 
ea345c145ff23197eab34d0c4d0c8a93d7bea8c6.

Is there any reason that the new ID should not have been sent to Stable as well, 
or was that an oversight?

Thanks,

Larry

Just adding a Cc: stable@... in the commit message is enough to get it
automatically queued once applied. Please check SubmittingPatches and
stable_kernel_rules.txt for more information.

It isn't absolutely clear to me that those rules applies to "wireless",
being a sub-subsystem of "net".  Quoting from stable_kernel_rules.txt :

"- If the patch covers files in net/ or drivers/net please follow netdev stable
   submission guidelines as described in
   Documentation/networking/netdev-FAQ.txt"

And the netdev-FAQ.txt goes into great detail describing the procedure,
which basically is "Give davem a hint that the patch should go to
stable".  (and I'd like to note that this works very well in practice).

But I have noticed that some stable patches seem to flow more directly
into stable from "wireless" than from the rest of "net". I just don't
think the current _written_ docs support that procedure.  Those docs
are possibly wrong?  You should probably know much better than me :)

I'd say that if it's something that you submit through the regular netdev
process, David will automatically handle the backports and feed stable if
he spots this is needed (hence sometimes some hints in the commit message
about what oldest version should benefit from the backport can help it get
properly spotted if there's any ambiguity). If you didn't go through that
process, there's almost no chance he will detect your work and propose it
and then it makes sense to Cc stable.

I know that sometimes it can be ambiguous, hence the benefit of being
the clearest possible in the commit message all the time so that anyone
could possibly detect that your work needs to be backported if it slips
through the process.

Willy

It is not necessary; however, it is best if it gets called to their attention. 
I'm not sure if my E-mail was the reason, but your patch was applied to several 
of the stable versions this morning. The rest will probably follow soon.

The easy way to do this is to add "Cc: Stable <stable@vger.kernel.org>" to the 
original patch at submission. That way, stable gets the message as soon as it 
goes into mainline.

Thanks,

Larry

Thanks Larry, I'll queue this patch for the 3.16 kernel.
