From 6f863e712d4114e8ae2f02de64ebeac0546ebaa0 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Mon, 1 Mar 2010 15:26:41 -0800 Subject: [PATCH] ceph: set osd request message front length correctly We didn't set the front length correctly. When messages used the message pool we ended up with the conservative max (4 KB), and the rest of the time the slightly less conservative estimate. Even though the OSD ignores the extra data, set it to the right value to avoid sending extra data over the network.
