clang can't evaluate this function argument at compile time when the
function is not inlined, which leads to a link time failure:
ld.lld: error: undefined symbol: __compiletime_assert_414
>>> referenced by mremap.c
>>> mremap.o:(get_extent) in archive mm/built-in.a
Mark the function as __always_inline to avoid it.

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.
