[dm-devel] 2.6.2-udm2

[Joe Thornber]

http://people.sistina.com/~thornber/dm/patches/2.6-unstable/2.6.2/2.6.2-udm2.tar.bz2

Big changes to the multipath target.

- The test interval is no longer passed in with the target parameters
  (tools writers take note.

- The kernel now does no path testing at all, let userland do it (see thread on lkml).

- Switch to work queues rather than dm-daemon (see other thread on lkml).
