I think this needs some justification.
Why is strscpy_pad() preferred in this case?

Also, assuming this is not a bug-fix for 'net', then it is an enhancement,
and should be targeted at net-next.

   Subject: [PATCH net-next] ...

As it stands, net-next is closed:

## Form letter - net-next-closed

The merge window for v6.6 has begun and therefore net-next is closed
for new drivers, features, code refactoring and optimizations.
We are currently accepting bug fixes only.

Please repost when net-next reopens after Sept 11th.

RFC patches sent for review only are obviously welcome at any time.

See: https://www.kernel.org/doc/html/next/process/maintainer-netdev.html#development-cycle

The line above is no longer indented correctly.
