    filesystem-dax: Set page->index · 73449daf
    Dan Williams authored
    In support of enabling memory_failure() handling for filesystem-dax
    mappings, set ->index to the pgoff of the page. The rmap implementation
    requires ->index to bound the search through the vma interval tree. The
    index is set and cleared at dax_associate_entry() and
    dax_disassociate_entry() time respectively.
