There is a new (req->flags & REQ_F_POLLED) check in __io_submit_flush_completions() for poll recycling, however io_free_batch_list() is a much better place for it. First, we prefer it after putting the last req ref just to avoid potential problems in the future. Also, it'll enable the recycling for IOPOLL and also will place it closer to all other req->flags bits clean up requests.

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.
