Consider the following scenario: 1. A freeze notification is delivered to thread 1. 2. The process becomes frozen or unfrozen. 3. The message for step 2 is delivered to thread 2 and ignored because there is already a pending notification from step 1. 4. Thread 1 acknowledges the notification from step 1. In this case, step 4 should ensure that the message ignored in step 3 is resent as it can now be delivered.

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 reStructuredText 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.
