Hi Linus, please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm tags/dax-fixes-4.20-rc6
...to receive the last of the known regression fixes and fallout from the Xarray conversion of the filesystem-dax implementation. On the path to debugging why the dax memory-failure injection test started failing after the Xarray conversion a couple more fixes for the dax_lock_mapping_entry(), now called dax_lock_page(), surfaced. Those plus the bug that started the hunt are now addressed. These patches have appeared in a -next release with no issues reported.
Note the touches to mm/memory-failure.c are just the conversion to the new function signature for dax_lock_page().
