      mm: fix pfn_t to page conversion in vm_insert_mixed · 03fc2da6
      Dan Williams 提交于
      pfn_t_to_page() honors the flags in the pfn_t value to determine if a
      pfn is backed by a page.  However, vm_insert_mixed() was originally
      written to use pfn_valid() to make this determination.  To restore the
      old/correct behavior, ignore the pfn_t flags in the !pfn_t_devmap() case
      and fallback to trusting pfn_valid().

      Dan Williams 提交于
      Dynamically enabling DAX requires that the page cache first be flushed
      and invalidated.  This must occur atomically with the change of DAX mode
      otherwise we confuse the fsync/msync tracking and violate data
      durability guarantees.  Eliminate the possibilty of DAX-disabled to
      DAX-enabled transitions for now and revisit this for the next cycle.
