Commiteeadcb7579("NFSD: Simplify READ_PLUS") replaced the use of write_bytes_to_xdr_buf(), copying what was in nfsd4_encode_read() at the time. However, the current code will corrupt the encoded data if the XDR data items that are reserved early and then poked into the XDR buffer later happen to fall on a page boundary in the XDR encoding buffer. __xdr_commit_encode can shift encoded data items in the encoding buffer so that pointers returned from xdr_reserve_space() no longer address the same part of the encoding stream.

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.
