Subject: [PATCH net-next 06/15] tools: ynl: make yarg the first member of struct ynl_dump_state
Date: Thu, 22 Feb 2024 15:56:05 -0800 [thread overview]
Message-ID: <20240222235614.180876-7-kuba@kernel.org> (raw)
In-Reply-To: <20240222235614.180876-1-kuba@kernel.org>
All YNL parsing code expects a pointer to struct ynl_parse_arg AKA yarg.
For dump was pass in struct ynl_dump_state, which works fine, because
struct ynl_dump_state and struct ynl_parse_arg have identical layout
for the members that matter.. but it's a bit hacky.
