Both KCOV and UBSAN use compiler instrumentation. If UBSAN detects a bug in KCOV, it may cause infinite recursion via printk and other common functions. We already don't instrument KCOV with KASAN/KCSAN for this reason, don't instrument it with UBSAN as well. As a side effect this also resolves the following gcc warning: conflicting types for built-in function '__sanitizer_cov_trace_switch'; expected 'void(long unsigned int, void *)' [-Wbuiltin-declaration-mismatch] It's only reported when kcov.c is compiled with any of the sanitizers enabled. Size of the arguments is correct, it's just that gcc uses 'long' on 64-bit arches and 'long long' on 32-bit arches, while kernel type is always 'long long'.

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.
