[dm-devel] [PATCH 0/3] dm-mpath: dynamic load balancers (v1)

[Kiyoshi Ueda]

Hi,

The patch-set adds the following 2 dynamic load balancers:
  o dm-queue-length: queue-length oriented dynamic load balancer
  o dm-service-time: service-time oriented dynamic load balancer

This patch-set can be applied on top of 2.6.29-rc8.
No dependencies on Alasdair's linux-next patches.

NOTE:
While the patches compile and work with the current bio-based dm,
for them to *properly* work, the request-based dm patches should
be applied, too.
See <http://lkml.org/lkml/2008/9/12/100> for why request-based dm
improves multipath load balancing.

Summary of the patch-set:
  1/3: dm-mpath: interface change for dynamic load balancers
  2/3: dm-mpath: add queue-length oriented dynamic load balancer
  3/3: dm-mpath: add service-time oriented dynamic load balancer
