## Form letter - net-next-closed

Linus already pulled net-next material v6.15 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 Apr 7th.

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