Hey Nick,

If you are out there, do not merge patches 5 - 20. I have a patchset
that will simplify things.

You should also drop

    tcmu: Oops in unmap_thread_fn()

    Calling list_del() on the iterator pointer in list_for_each_entry() will
    cause an oops.  We need to user the _safe() version for that.

from your for-next branch. That first patch added several regressions
and the second patch is then not needed. My new patchset will fix the
starvation issue.
