As you noticed I already send out a patch, I can send a new with your pattern, as it seems to be faster. -- Best regards, Jesper Dangaard Brouer MSc.CS, Principal Kernel Engineer at Red Hat LinkedIn: http://www.linkedin.com/in/brouer

I think it is a good idea to change the keyword (K:), but I'm not sure this catch what we want, maybe it does. The pattern match are meant to catch drivers containing XDP related bits. Previously Joe Perches suggested this pattern match, which I don't fully understand... could you explain Joe? (?:\b|_)xdp(?:\b|_) For the filename (N:) regex match, I'm considering if we should remove it and list more files explicitly. I think normal glob * pattern works, which should be sufficient. -- Best regards, Jesper Dangaard Brouer MSc.CS, Principal Kernel Engineer at Red Hat LinkedIn: http://www.linkedin.com/in/brouer

I agree that sparing xdp from hwmon patches is a good thing :)

Agreed, we should fix this. For maintainers with high patch volume life would be so much easier if people CCed the right folks to get reviews, so we should try our best to fix get_maintainer. XDP folks, any opposition to changing the keyword / filename to: [^a-z0-9]xdp[^a-z0-9] ?

Given xdp maintainers were included by mistake, I will remove them from the future discussions of this hwmon patch series. Cheers, Tao

Now we know this, we can figure out why it is adding all these extra addresses which make no sense. Maybe a bug in the MAINTAINERS file? Andrew

I have no idea why running get_maintainer.pl on Documentation/hwmon/index.rst returns such a large list of mailing lists and people. For some reason it includes everyone in the XDP maintainer list. If anyone has an idea how that happens, please let me know - we'll want to get this fixed to avoid the same problem in the future. Guenter
