The differences between iterate_iovec and iterate_kvec are minor: * kvec callback is treated as if it returned 0 * initialization of __p is with i->iov and i->kvec resp. which is trivially dealt with. No code generation changes - compiler is quite capable of turning left = ((void)(STEP), 0); __v.iov_len -= left; (with no accesses to left downstream) and (void)(STEP); into the same code.

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.
