Linus Torvalds b1b11d0063 cleanup in-kernel read and write operations
Reshuffle the (__)kernel_read and (__)kernel_write helpers, and ensure
 all users of in-kernel file I/O use them if they don't use iov_iter
 based methods already.

Merge tag 'cleanup-kernel_read_write' of git://git.infradead.org/users/hch/misc

Pull in-kernel read and write op cleanups from Christoph Hellwig:
 "Cleanup in-kernel read and write operations

  Reshuffle the (__)kernel_read and (__)kernel_write helpers, and ensure
  all users of in-kernel file I/O use them if they don't use iov_iter
  based methods already.

  The new WARN_ONs in combination with syzcaller already found a missing
  input validation in 9p. The fix should be on your way through the
  maintainer ASAP".

[ This is prep-work for the real changes coming 5.9 ]

README

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.
