Both KASAN and KCOV had issues with LTO_CLANG if DEBUG_INFO is enabled. With LTO inlinable function calls are required to have debug info if they are inlined into a function that has debug info. Starting with LLVM 17 this will be fixed ([1],[2]) and enabling LTO with KASAN/KCOV and DEBUG_INFO doesn't cause linker errors anymore.

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.
