Clang gets rather confused about two variables in the same special section when one of them is not initialized, leading to an assembler warning later: /tmp/slab_common-18f869.s: Assembler messages: /tmp/slab_common-18f869.s:7526: Warning: ignoring changed section attributes for .data..ro_after_init Adding an initialization to kmalloc_caches is rather silly here but does avoid the issue.

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.
