I can no longer build lustre against the latest upstream zfs source pulled from the master branch of github.com/behlendorf/zfs.git. A recent commit has eliminated the internal API dsl_prop_set() used in osd-zfs code.

This is not currently a problem in our build and test framework where builds are done against an earlier, fixed, and frozen version of zfs source. It will become a problem the next time we sync up to the latest upstream zfs version.
