The open code is defined as a helper function(netdev_unregistering)
on netdev.h, which the open code is dev->reg_state == NETREG_UNREGISTERING.
Thus, netdev_unregistering() replaces the open code. This patch doesn't
change logic.

The open code is defined as a helper function(netdev_unregistering)
on netdev.h, which the open code is dev->reg_state == NETREG_UNREGISTERING.
Thus, netdev_unregistering() replaces the open code. This patch doesn't
change logic.

Is there any value in adding a netdev_registered() helper?

The open code which is reg_state == NETREG_REGISTERED used 37 times on
some codes related to the network. I think that the
netdev_registered() helper is valuable.

Thanks!
Apart from this patch, is it okay to send a patch that adds the
netdev_registered helper function later?

In my opinion that would be good: let's fix one thing at a time.

I agree with you.
I will send a patch by applying netdev_registered() helper function by
directory.

Please hold off doing that. My preference would be to remove
netdev_unregistering(), this is all low-gain churn.
IMHO the helpers don't add much to readability and increase
the number of random helpers programmer must be aware of.
Let me check with other netdev maintainers and get back to you.

I got hold of Paolo and he concurred. Let's remove
netdev_unregistering() instead. Thanks!

Thank you for your review!
I will send the next version which includes removing netdev_unregistering()
as soon as possible.
Best regards,
