Matthew Wilcox says:
====================
Convert skb_frag_t to bio_vec
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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
