From: "Matthew Wilcox (Oracle)" <wi...@infradead.org>
The skb_frag_t and bio_vec are fundamentally the same (page, offset,
length) tuple. This patch series unifies the two, leaving the
skb_frag_t typedef in place. This has the immediate advantage that
we already have iov_iter support for bvecs and don't need to add
support for iterating skbuffs. It enables a long-term plan to use
bvecs more broadly within the kernel and should make network-storage
drivers able to do less work converting between skbuffs and biovecs.
It will consume more memory on 32-bit kernels. If that proves
problematic, we can look at ways of addressing it.
v3: Rebase on latest Linus with net-next merged.
- Reorder the uncontroversial 'Use skb accessors' patches first so you
can apply just those two if you want to hold off on the full
conversion.
- Convert all the users of 'struct skb_frag_struct' to skb_frag_t.
Matthew Wilcox (Oracle) (7):

net: Reorder the contents of skb_frag_t
net: Rename skb_frag page to bv_page
net: Rename skb_frag_t size to bv_len
net: Convert skb_frag_t to bio_vec
