'inline' keyword is only a recommendation for compiler. If it decides to
not inline find_bit nodemask functions, the whole small_const_nbits()
machinery doesn't work.
This is how a standard GCC 11.3.0 does for my x86_64 build now. This patch
replaces 'inline' directive with unconditional '__always_inline' to make
sure that there's always a chance for compile-time optimization. It doesn't
change size of kernel image, according to bloat-o-meter.

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.
