Subject: [PATCH net-next 3/9] tipc: change sk_receive_queue upper limit
Date: Fri, 7 Dec 2012 20:19:12 -0500 [thread overview]
Message-ID: <1354929558-16948-4-git-send-email-paul.gortmaker@windriver.com> (raw)
In-Reply-To: <1354929558-16948-1-git-send-email-paul.gortmaker@windriver.com>
From: Jon Maloy <jon.maloy@ericsson.com>
The sk_recv_queue upper limit for connectionless sockets has empirically
turned out to be too low. When we double the current limit we get much
fewer rejected messages and no noticable negative side-effects.
