This is a note to let you know that I have just added a patch titled libceph: drop connection refcounting for mon_client to the linux-3.5.y-queue branch of the 3.5.yuz extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.yuz tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Herton ------ From 5d2ed52fdf92034887ac74d1e8d3aa9a5c24fb8a Mon Sep 17 00:00:00 2001 From: Sage Weil <sage@inktank.com> Date: Thu, 31 May 2012 20:27:50 -0700 Subject: [PATCH 11/78] libceph: drop connection refcounting for mon_client commit ec87ef4309d33bd9c87a53bb5152a86ae7a65f25 upstream. All references to the embedded ceph_connection come from the msgr workqueue, which is drained prior to mon_client destruction. That means we can ignore con refcounting entirely.
