For more information about the 3.5.yuz tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Herton ------ >From c701826d9cb65a09446c7fe1618fe77ede22b063 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Tue, 22 May 2012 11:41:43 -0500 Subject: [PATCH 03/78] libceph: rename socket callbacks commit 327800bdc2cb9b71f4b458ca07aa9d522668dde0 upstream. Change the names of the three socket callback functions to make it more obvious they're specifically associated with a connection's socket (not the ceph connection that uses it).
