Subject: [PATCH nf-next 2/5] netfilter: ecache: remove another indent level
Date: Mon, 16 Aug 2021 17:16:23 +0200 [thread overview]
Message-ID: <20210816151626.28770-3-fw@strlen.de> (raw)
In-Reply-To: <20210816151626.28770-1-fw@strlen.de>
... by changing:
if (unlikely(ret < 0 || missed)) {
if (ret < 0) {
to
if (likely(ret >= 0 && !missed))
goto out;
if (ret < 0) {
After this nf_conntrack_eventmask_report and nf_ct_deliver_cached_events
look pretty much the same, next patch moves common code to a helper.
This patch has no effect on generated code.
