Do checks on the returned inq counter. Fail on: 1. Huge value (> 1 kbyte, test case files are 1 kb) 2. last hint larger than returned bytes when read was short 3. erronenous indication of EOF. 3) happens when a hint of X bytes reads X-1 on next call but next recvmsg returns more data (instead of EOF).

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.
