There is already an error inside that header: #if !defined(__LINUX_SPINLOCK_TYPES_H) # error "Do not include directly, include spinlock_types.h" #endif Thankfully it never get triggered as some other headers have already included spinlock_types.h. However clangd would still do a proper warning on that if only extent_map.h is opened. Fix it by using spinlock_types.h instead.

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.
