The restriction on multishot execution context disallowing io-wq is driven by rules of io_fill_cqe_req_aux(), it should only be called in the master task context, either from the syscall path or in task_work. Since task_work now always takes the ctx lock implying IO_URING_F_COMPLETE_DEFER, we can just assume that the function is always called with its defer argument set to true. Kill the argument. Also rename the function for more consistency as "fill" in CQE related functions was usually meant for raw interfaces only copying data into the CQ without any locking, waking the user and other accounting "post" functions take care of.

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.
