DO_ONCE(func, ...) will call func with spinlock which acquired by
spin_lock_irqsave in __do_once_start. But the get_random_once_wait will
sleep in get_random_bytes_wait -> wait_for_random_bytes.
Fortunately, there is no place to use {net_}get_random_once_wait, so we
could remove them simply.

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.
