Description
lustre server builds with zfs using the most recent master versions of spl and zfs fail in osd-zfs. this problem isn't seen when building with a fixed version of 0.6.3 or earlier of spl, so it must be due to very recent changes. not a blocker as long as we build with a fixed version of spl that works, but will become a problem the next time we move to later tagged versions.
looks like the underlying cause is conflicting defn's of SHRINK_STOP in spl #includes and lustre #includes. example errors:
