Currently, io_uring's io_sg_from_iter() duplicates the part of __zerocopy_sg_from_iter() charging pages to the socket. It'd be too easy to miss while changing it in net/, the chunk is not the most straightforward for outside users and full of internal implementation details. io_uring is not a good place to keep it, deduplicate it by moving out of the callback into __zerocopy_sg_from_iter().

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 reStructuredText 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.
