There is no reason not to use __io_cq_unlock_post_flush for intermediate aux CQE flushing, all ->task_complete should apply there, i.e. if set it should be the submitter task. Combine them, get rid of of __io_cq_unlock_post() and rename the left function. This place was also taking a couple percents of CPU according to profiles for max throughput net benchmarks due to multishot recv flooding it with completions.

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.
