On older kernels (5.4 and older), building the kernel with clang can cause the section name to end up with "" in them, which can cause lots of runtime issues as that is not normally a valid portion of the string. This was fixed up in newer kernels with commit33def8498f("treewide: Convert macro and uses of __section(foo) to __section("foo")") but that's too heavy-handed for older kernels. So for now, fix up the problem that commit62c07983be("once: add DO_ONCE_SLOW() for sleepable contexts") caused by being backported by removing the "" characters from the section definition.

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.
