Subject: [PATCH net-next 01/15] net: bridge: mdb: arrange internal structs so fast-path fields are close
Date: Mon, 31 Aug 2020 18:08:31 +0300	[thread overview]
Message-ID: <20200831150845.1062447-2-nikolay@cumulusnetworks.com> (raw)
In-Reply-To: <20200831150845.1062447-1-nikolay@cumulusnetworks.com>

Before this patch we'd need 2 cache lines for fast-path, now all used
fields are in the first cache line.
