There is already a macro DEFINE_WAIT_FUNC() to declare a wait_queue_entry with a specified waking function. But there is not a counterpart for initializing one wait_queue_entry with a specified waking function. So introducing init_wait_func() for this, which also could be used in iocost and rq-qos. Using default_wake_function() in rq_qos_wait() to wake up waiters, which could remove ->task field from rq_qos_wait_data.

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.
