The RPC code is occasionally hanging when the receive code fails to empty the socket buffer due to a partial read of the data. When we convert that to an EAGAIN, it appears we occasionally leave data in the socket. The fix is to just keep reading until the socket returns EAGAIN/EWOULDBLOCK.

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.
