But if it is net-next, which seems likely given the code under drivers/net/, then: Please include that target in the subject of each patch in the patch-set. Subject: [PATCH v5 net-next 0/5] ... And, moreover, ... ## Form letter - net-next-closed The merge window for v6.16 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 June 8th. RFC patches sent for review only are obviously welcome at any time.
