[dm-devel] [PATCH RFC 1/5] add support for manual failover devices

[Mike Christie]

01-ps-failpath.patch - move the path failure decision to the path
selector. Some ps's may want to select paths that have a couple
failures over one that has N failures. If a ps has to track this info
there didn't seem to be a compelling reason to also do it in
dm-mpath.c. Well code duplication and sharing is a good reason to do
it at dm-mpath. It would be nice if I could just add an init function
to any ps and leach off other people's work :) but is that too modular?

Additionally, if a ps fails to activate a path or cannot use it
during initialization it may want to fail it.
