Pass only non-null @nxt to io_issue_sqe() and handle it at the caller's side. And propagate it. - kiocb_done() is only called from io_read() and io_write(), which are only called from io_issue_sqe(), so it's @nxt != NULL - io_put_req_find_next() is called either with explicitly non-null local nxt, or from one of the functions in io_issue_sqe() switch (or their callees).

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.
