This patch was dropped because it was folded into per-task-delay-accounting-taskstats-interface-control-exit-data-through-cpumasks.patch
------------------------------------------------------
Subject: per task delay accounting taskstats interface: fix drop listener only on socket close
From: Shailabh Nagar <nagar@xxxxxxxxxxxxxx>
Remove listeners from per-cpu listener lists only if they've closed the socket
(resulting in an ECONNREFUSED failure of genetlink unicast). For other errors
returned by genlmsg_unicast like -EAGAIN which results from the receiver's
buffer having insufficient space, userspace gets an ENOBUF warning and the
kernel can continue.
