Subject: [PATCH v3 27/30] ipv4: frags: precedence bug in ip_expire()
Date: Thu, 13 Sep 2018 07:58:59 -0700 [thread overview]
Message-ID: <20180913145902.17531-28-sthemmin@microsoft.com> (raw)
In-Reply-To: <20180913145902.17531-1-sthemmin@microsoft.com>
From: Dan Carpenter <dan.carpenter@oracle•com>
We accidentally removed the parentheses here, but they are required
because '!' has higher precedence than '&'.
Fixes: fa0f527358bd ("ip: use rb trees for IP frag queue.")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle•com>

(cherry picked from commit 70837ffe3085c9a91488b52ca13ac84424da1042)
