[PATCH 0/3] Make pfn_t suitable for placing in the radix tree

[Matthew Wilcox]

I did some experimenting with converting the DAX radix tree from storing
sector numbers to storing pfn_t.  While we're not ready to do that
conversion yet, these pieces make sense to at least get reviewed now,
and maybe get upstream.

I think the first patch is worthwhile all by itself as a stepping stone to
making SG lists contain PFNs instead of pages.

Matthew Wilcox (3):
  pfn_t: Change the encoding
  pfn_t: Support for huge PFNs
  pfn_t: New functions pfn_t_add and pfn_t_cmp
