[dm-devel] [PATCH 0/3] dm-mpath: dynamic load balancers (v2)



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 2.6.30-rc3.
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://marc.info/?l=dm-devel&m=123736590931733&w=2> 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
