[PATCH v2 6/6] cdx: MAINTAINERS: Explicitly mention Greg who handles patches

[PATCH v2 6/6] cdx: MAINTAINERS: Explicitly mention Greg who handles patches
Posted by Krzysztof Kozlowski 9 months, 2 weeks ago 
Patches for CDX bus drivers are applied by Greg Kroah-Hartman, so list
him in the maintainers entry because otherwise contributors would be
surprised their patches got lost.

Sorry, but no, I'm not the maintainer of this driver.  It's up to the
maintainer(s) of it to send me the patches on to be merged, it is not up
to me to maintain the code at all.

thanks,

Sure, I understand. I  will send a v3 without maintainers patch and I
assume the maintainers will pick them up (unless drivers are orphaned).

And now I found this:
https://lore.kernel.org/lkml/929198a2-6b3b-0f1b-3f36-cd8955ca6f19@amd.com/

"We do not maintain a tree and  patches go via Greg's tree."

which means that patches won't be picked up. Your email does not pop up
on b4/get_maintainers. Overall this means cdx driver might be abandoned,
from contributors point of view.

If that's the case I will send a patch making this orphaned.

More patches which never received any attention or were not picked up:

We usually copy Greg once the patches are reviewed/acked from our side 
if he is not already on the list. Do you suggest any alternate approach 
in maintaining the drivers like cdx which do not have their own tree?

This is applied on the Linux tree.

This is also applied on the Linux tree.

Either you have the tree or person having the tree appears on
maintainers output. There is no other option.

If you refuse to take the patches and handle them, I claim this is
orphaned from the kernel point of view, even if occasionally Greg takes
these. I believe Greg was already pointing this issue more than once.

Yeah, but no reviews were given.

Same here.

It already has been one week, but I guess two weeks is still acceptable
for hobbyist. For company-related maintainership not really.

You are CC-ed on these Typec alternate modes, as the subsystem
maintainer or patches-picking-up-maintainer:

*  1 Heikki Krogerus <heikki.krogerus@linux.intel.com>
     maintainer:USB TYPEC BUS FOR ALTERNATE MODES
*  2 Greg Kroah-Hartman <gregkh@linuxfoundation.org>
     maintainer:USB SUBSYSTEM

Here, you are not Cced at all. That's why this is different.

It is basically the only one subsystem doing that way.

Basically this looks like incomplete subsystem or a driver without
subsystem. With the different that we have many per-driver entries but
they are part of some subsystem maintainer's scope.

I agree they are handling them. I disagree this is totally normal that
get_maintainers.pl does not point out the actual subsystem/maintainer
handling the patches.

If I remember correctly, it was Linus who said he uses
`get_maintainer.pl -f FILE/PATH`, so with his workflow he would not get
the maintainer's address (yours). One would have to go through git
history to look for SoB, but that's not normal process.

That's an exception.
