[dm-devel] [RFC PATCH 0/4] dm-mpath: dynamic load balancers



Hi,

The following patches add the following 2 dynamic load balancers
to request-based dm-multipath:
  o queue-length oriented dynamic load balancer, dm-queue-length.
  o service-time oriented dynamic load balancer, dm-service-time.

This patch-set is not ready for inclusion to the upstream kernel,
but I'm posting now to hear comments from multipath related people.
Any comments are welcome.

This patch-set can be applied on top of 2.6.27-rc6 + Alasdair's
linux-next patches below + request-based dm patches(*).
    dm-mpath-use-more-error-codes.patch
    dm-mpath-remove-is_active-from-struct-dm_path.patch

(*) http://lkml.org/lkml/2008/9/12/100


Summary of the patch-set:
  1/4: dm-mpath: add a path-selector interface
  2/4: dm-mpath: add queue-length oriented dynamic load balancer (dlb)
  3/4: dm-mpath: interface change for service-time oriented dlb
  4/4: dm-mpath: add service-time oriented dynamic load balancer (dlb)

Thanks,
Kiyoshi Ueda
