needs_async_data controls allocation of async_data, and used in two cases. 1) when async setup requires it (by io_req_prep_async() or handler themselves), and 2) when op always needs additional space to operate, like timeouts do. Opcode preps already don't bother about the second case and do allocation unconditionally, restrict needs_async_data to the first case only and rename it into needs_async_setup.

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.
