Message-ID: <20241003205248.61445-1-donald.hunter@gmail.com> Date: Thu, 3 Oct 2024 21:52:48 +0100 From: Donald Hunter <donald.hunter@...il.com> To: netdev@...r.kernel.org, Jakub Kicinski <kuba@...nel.org>, "David S. Miller" <davem@...emloft.net>, Eric Dumazet <edumazet@...gle.com>, Paolo Abeni <pabeni@...hat.com>, linux-doc@...r.kernel.org, Jonathan Corbet <corbet@....net> Cc: donald.hunter@...hat.com, Donald Hunter <donald.hunter@...il.com> Subject: [PATCH net-next v1] doc: net: Fix .rst rendering of net_cachelines pages The doc pages under /networking/net_cachelines are unreadable because they lack .rst formatting for the tabular text. Add simple table markup and tidy up the table contents: - remove dashes that represent empty cells because they render as bullets and are not needed - replace 'struct_*' with 'struct *' in the first column so that sphinx can render links for any structs that appear in the docs Signed-off-by: Donald Hunter <donald.hunter@...il.com> --- .../net_cachelines/inet_connection_sock.rst | 86 ++---
