Subject: [PATCH net-next v2 01/15] net: bridge: mdb: arrange internal structs so fast-path fields are close
Date: Wed, 2 Sep 2020 14:25:15 +0300 [thread overview]
Message-ID: <20200902112529.1570040-2-nikolay@cumulusnetworks.com> (raw)
In-Reply-To: <20200902112529.1570040-1-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.
