Subject: [PATCH net-next 11/13] genetlink: inline old iteration helpers
Date: Tue, 18 Oct 2022 16:07:26 -0700	[thread overview]
Message-ID: <20221018230728.1039524-12-kuba@kernel.org> (raw)
In-Reply-To: <20221018230728.1039524-1-kuba@kernel.org>

All dumpers use the iterators now, inline the cmd by index
stuff into iterator code.
