zfs_20070303.patch on current

[Andrei Kolu]

Now I found out why my kernel build failed. I followed directions found in 
patch file:

# patch -p0 < zfs_20070303.patch
# make kernel
# cd cddl
# make && make install
Build failed.

Then I changed it to this:

# patch -p0 < zfs_20070303.patch
# make buildkernel
# cd cddl
# make && make install
# make installkernel

Now I got working kernel but ZFS is still not available:

# zpool status
internal error: failed to initialize ZFS library
