[ Upstream commit6c254bf3b6] I found that NFSD's new NFSv3 READDIRPLUS XDR encoder was screwing up right at the end of the page array. xdr_get_next_encode_buffer() does not compute the value of xdr->end correctly: * The check to see if we're on the final available page in xdr->buf needs to account for the space consumed by @nbytes. * The new xdr->end value needs to account for the portion of @nbytes that is to be encoded into the previous buffer.

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.
