The initial-breadcrumb is used to mark the end of the awaiting and the beginning of the user payload. We verify that we do not start the user payload before all signaler are completed, checking our semaphore setup by looking for the initial breadcrumb being written too early. We also want to ensure that we do not add semaphore waits after we have already closed the semaphore section, an issue for later deferred waits.

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.
