Currently we never clear dirty tags in DAX mappings and thus address
ranges to flush accumulate. Now that we have locking of radix tree
entries, we have all the locking necessary to reliably clear the radix
tree dirty tag when flushing caches for corresponding address range.
Similarly to page_mkclean() we also have to write-protect pages to get a
page fault when the page is next written to so that we can mark the
entry dirty again.

Looks great.

Thanks for review Ross! I've rebased the series on top of rc1. Do you have
your PMD series somewhere rebased on top of rc1 so that I can rebase my
patches on top of that as well? Then I'd post another version of the
series...

Sure, I'll rebase & post a new version of my series today.
