io_zc_rx_tcp_recvmsg() continues until it fails or there is nothing to receive. If the other side sends fast enough, we might get stuck in io_zc_rx_tcp_recvmsg() producing more and more CQEs but not letting the user to handle them leading to unbound latencies. Break out of it based on an arbitrarily chosen limit, the upper layer will either return to userspace or requeue the request.

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.
