Olivier Langlois 2c762be5b7 io_uring: keep multishot request NAPI timeout current
This refresh statement was originally present in the original patch:
https://lore.kernel.org/netdev/20221121191437.996297-2-shr@devkernel.io/

It has been removed with no explanation in v6:
https://lore.kernel.org/netdev/20230201222254.744422-2-shr@devkernel.io/

It is important to make the refresh for multishot requests, because if no
new requests using the same NAPI device are added to the ring, the entry
will become stale and be removed silently. The unsuspecting user will
not know that their ring had busy polling for only 60 seconds before
being pruned.

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.
