Subject: [PATCH 0/3] Make pfn_t suitable for placing in the radix tree
Date: Fri, 11 Mar 2016 16:13:01 -0500 [thread overview]
Message-ID: <1457730784-9890-1-git-send-email-matthew.r.wilcox@intel.com> (raw)
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
