Dave Wysochanski 4797ad1f56 NFS: Fix /proc/PID/io read_bytes for buffered reads 
[ Upstream commit 9c88ea00fe ]

Prior to commit 8786fde842 ("Convert NFS from readpages to
readahead"), nfs_readpages() used the old mm interface read_cache_pages()
which called task_io_account_read() for each NFS page read.  After
this commit, nfs_readpages() is converted to nfs_readahead(), which
now uses the new mm interface readahead_page().  The new interface
requires callers to call task_io_account_read() themselves.
In addition, to nfs_readahead() task_io_account_read() should also
be called from nfs_read_folio().

Fixes: 8786fde842 ("Convert NFS from readpages to readahead")

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.
