====================
IPVS fixes for net

The following batch contains IPVS fixes for net to address issues
from the latest net-next pull request.

Julian Anastasov made the following summary:

1-3) Fixes for the recently added resizable hash tables

4) dest from trash can be leaked if ip_vs_start_estimator() fails

5) fixed races and locking for the estimation kthreads

6) fix for wrong roundup_pow_of_two() usage in the resizable hash
   tables

7-8) v2 of the changes from Waiman Long to properly guard against
  the housekeeping_cpumask() updates:

  I added missing Fixes tag. The original description:

  Since commit 041ee6f3727a ("kthread: Rely on HK_TYPE_DOMAIN for preferred
  affinity management"), the HK_TYPE_KTHREAD housekeeping cpumask may no
  longer be correct in showing the actual CPU affinity of kthreads that
  have no predefined CPU affinity. As the ipvs networking code is still
  using HK_TYPE_KTHREAD, we need to make HK_TYPE_KTHREAD reflect the
  reality.

  This patch series makes HK_TYPE_KTHREAD an alias of HK_TYPE_DOMAIN
  and uses RCU to protect access to the HK_TYPE_KTHREAD housekeeping
  cpumask.

Julian plans to post a nf-next patch to limit the connections by using
"conn_max" sysctl. With Simon Horman, they agreed that this is an old
problem that we do not have a limit of connections and it is not a
stopper for this patchset.
