Subject: [PATCH net-next 1/6] netconsole: introduce 'release' as a new
 sysdata field

This commit adds a new feature to the sysdata structure, allowing the
kernel release/version to be appended as part of sysdata. Additionally,
it updates the logic to count this new field as a used entry when
enabled.
