Thank you for porting of ZFS.
I tried to run your code on FreeBSD/amd64 and it seems running very well.
It survives several "make -j8 buildworld/kernel" with the obj tree in ZFS.
Here is what I did,
1. copy files from //depot/user/pjd/zfs/...
(without vop_vptofh related changes)
2. delete sys/contrib/opensolaris/uts/common/sys/acl.h
3. add sys/contrib/opensolaris/uts/common/rpc/types.h from opensolaris
(for vaild declaration of mem_alloc/mem_free for kernel)
4. replace "i386" in sys/modules/zfs/Makefile with ${MACHINE}.
5. apply the following patch.
6. build
