commit 8f1d3b68ff08466f55c55e03f9aa4d989c515095 (powerpc/powernv : Drop reference added by kset_find_obj()) was released in UBUNTU: Ubuntu-4.4.0-39.59 which never made it out of proposed. It has since been superseded by Ubuntu-4.4.0-41.61 due to regressions respins. That is the version that you should be verifying.

Ojha <mukeo...@in.ibm.com> - 2016-09-02 02:12:45 == Upstream commit : commit a9cbf0b2195b695cbeeeecaa4e2770948c212e9a Author: Mukesh Ojha <mukes...@linux.vnet.ibm.com> Date: Mon Aug 22 12:17:44 2016 +0530 powerpc/powernv : Drop reference added by kset_find_obj() In a situation, where Linux kernel gets notified about duplicate error log from OPAL, it is been observed that kernel fails to remove sysfs entries (/sys/firmware/opal/elog/0xXXXXXXXX) of such error logs. This is because, we currently search the error log/dump kobject in the kset list via 'kset_find_obj()' routine. Which eventually increment the reference count by one, once it founds the kobject. Above patch is the solution of this bugzilla. Kindly pull this patch in for both Ubuntu 16.04 LTS and Ubuntu 16.10. -Mukesh To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1619552/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
