Subject[PATCH 0/2] Write protect DAX PMDs in *sync path
Currently dax_mapping_entry_mkclean() fails to clean and write protect the
pmd_t of a DAX PMD entry during an *sync operation. This can result in
data loss, as detailed in patch 2.

This series is based on Dan's "libnvdimm-pending" branch, which is the
current home for Jan's "dax: Page invalidation fixes" series. You can find
a working tree here:

Ross Zwisler (2):
mm: add follow_pte_pmd()
dax: wrprotect pmd_t in dax_mapping_entry_mkclean
