Somehow, I'm not able to reproduce the warnings... Anyway, I think I see
what's going on. Can you check whether the warning goes away when you
change the condition at the end of page_cache_tree_delete() to:

        if (!dax_mapping(mapping) && !workingset_node_pages(node) &&
            list_empty(&node->private_list)) {

Yep, this took care of both of the issues that I reported.  I'll restart my
testing with this in my baseline, but as of this fix I don't have any more
open testing issues. :)

Well, looks like I spoke too soon.  The two tests that were failing for me are
now passing, but I can still create what looks like a related failure using
XFS, DAX, and the two xfstests generic/231 and generic/232 run back-to-back.

Hum, full xfstests run completes for me just fine. Can you reproduce the
issue with the attached debug patch? Thanks!
