If there are badblocks present in the 'struct page' area for pfn namespaces, until now, the only way to clear them has been to force the namespace into raw mode, clear the errors, and re-enable the fsdax mode. This is clunky, given that it should be easy enough for the pfn driver to do the same. Add a new helper that uses the most recently available badblocks list to check whether there are any badblocks that lie in the volatile struct page area. If so, before initializing the struct pages, send down targeted writes via nvdimm_write_bytes to write zeroes to the affected blocks, and thus clear errors.
