In several places the same code is used to populate rtnl_link_stats64
fields with data from pcpu_sw_netstats. Therefore factor out this code
to a new function dev_fetch_sw_netstats().

v2:
- constify argument netstats
- don't ignore netstats being NULL or an ERRPTR
- switch to EXPORT_SYMBOL_GPL

Jakub,

Is it possible to make sure that changelogs are not part of the commit
messages? We don't store previous revisions in the git repo, so it doesn't
give too much to anyone who is looking on git log later. The lore link
to the patch is more than enough.

44fa32f008ab ("net: add function dev_fetch_sw_netstats for fetching pcpu_sw_netstats")

Thanks

I remember that once I did it the usual way (changelog below the ---) David
requested the changelog to be part of the commit message. So obviously he
sees some benefit in doing so.

Do you have a link? What is the benefit and how can we use it?

Usually such request comes to ensure that commit message is updated with
extra information (explanation) existed in changelog which is missing in
the patch.

Thanks

There was also a long discussion a year or so back, starting at

So why is it usable?
The combination of Link, b4 and git range-diff gives everything in much
more reliable way.
