Subject: [PATCH net 2/3] netlink: add nl_set_extack_cookie_u32()
Date: Sun, 15 Mar 2020 18:17:48 +0100 (CET) [thread overview]
Message-ID: <1c58a7ea30236aedbd0f87611778878071b0b4a6.1584292182.git.mkubecek@suse.cz> (raw)
In-Reply-To: <cover.1584292182.git.mkubecek@suse.cz>
Similar to existing nl_set_extack_cookie_u64(), add new helper
nl_set_extack_cookie_u32() which sets extack cookie to a u32 value.
