[systemd-devel] [PATCH] journal: Leave server_dispatch_message early when Storage is none

[Holger Hans Peter Freyther]

From: Holger Hans Peter Freyther <holger at moiji-mobile.com>

When using Storage=none there is no point in collecting all the
information just to throw them away. After this change journald
consumes a lot less CPU time when only forwarding messages.
