Since syzkaller continues various test cases until the kernel crashes, syzkaller tends to examine more locking dependencies than normal systems. As a result, syzbot is reporting that the fuzz testing was terminated due to hitting upper limits lockdep can track [1] [2] [3]. Since analysis via /proc/lockdep* did not show any obvious culprit [4] [5], we have no choice but allow tuning tracing capacity constants.

README
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.
