Jens Axboe 40f45fe8eb userfaultfd: convert to ->read_iter()
Rather than use the older style ->read() hook, use ->read_iter() so that
userfaultfd can support both O_NONBLOCK and IOCB_NOWAIT for non-blocking
read attempts.

Split the fd setup into two parts, so that userfaultfd can mark the file
mode with FMODE_NOWAIT before installing it into the process table. With
that, we can also defer grabbing the mm until we know the rest will
succeed, as the fd isn't visible before then.

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.
