I plan to start committing stuff bit-by-bit starting a week from now, subject to review of the bits. As part of this work I will be moving the CDDL sources that ZFS uses into a separate CDDL-specific tree according to core@ instructions (resulting from their license review). There will also be minor changes to ZFS to build some things in an 'opensolaris' kernel module which are shared with DTrace. Both the zfs and dtrace kernel modules will depend on the opensolaris module. I am not planning to commit all of DTrace in one big blob. Instead I want to get the changes in without enabling them in the build right away. The DTrace support is optional, so I'll try not to break the build. (famous last words?) -- John Birrell
