Currently gcc seems to inline devtmpfs_setup() into devtmpfsd(), so its memory footprint isn't reclaimed as intended. Mark it noinline to make sure it gets put in .init.text. While here, setup_done can also be put in .init.data: After complete() releases the internal spinlock, the completion object is never touched again by that thread, and the waiting thread doesn't proceed until it observes ->done while holding that spinlock. This is now the same pattern as for kthreadd_done in init/main.c: complete() is done in a __ref function, while the corresponding wait_for_completion() is in an __init function.

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.
