[Qemu-devel] Question: Perfecting checkpatch.pl

[Aleksandar Markovic]

Perhaps checkpatch.pl should make sure the commit messages do not contain "address@hidden" and "Reviewed-off-by"?

$ git log | grep address@hidden
    Signed-off-by: Michael S. Tsirkin <address@hidden>
    Signed-off-by: Ronald Hecht <address@hidden>
    Signed-off-by: Justin Chevrier <address@hidden>
    Signed-off-by: Justin Chevrier <address@hidden>
    Signed-off-by: Justin Chevrier <address@hidden>

$ git log | grep Reviewed-off-by
    Reviewed-off-by: Pavel Dovgalyuk <pavel.dovgaluk@ispras.ru>
    Reviewed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Sure, both are good ideas.  Can you write a patch for it?

I would rather not, I prefer to see it as a black box.

So do most of the rest of us :-)  This is why sometimes
it does not have all the features that might seem nice for
it to have...

Having a check for that is a good idea, but I don't think checkpatch 
would help, these incorrect emails only appear once maintainer applied 
patches, maybe the good place to check would be Peter's magic scripts, see:
https://git.linaro.org/people/peter.maydell/misc-scripts.git/tree/apply-pullreq?id=eeb001fcc1aabd8f077cd2846724120a3aa8f962#n118

Those emails also entered the tree:

hw/usb/hcd-ehci.c:4: * Copyright(c) 2008  Emutex Ltd. (address@hidden)
include/qemu/pmem.h:6: * Author: Haozhong Zhang <address@hidden>

This makes sense...

but I'm not convinced it is worth doing this, because the set of
mistakes people have made is enourmous, so it turns into a game
of whack-a-mole.

You could have checkpatch whitelist the sensible ones:

>   30991 Reviewed-by
>   97837 Signed-off-by

and warn about the rest...

I guess warning would be ok - I don't want to discourage people from
being creative and "singing off" their patches :-)
