With the update of the permanent and intermittent health errors, the
actual indicator for the health test indicates a potential error only
for the one offending time stamp gathered in the current iteration
round. The next iteration round will "overwrite" the health test result.
Thus, the entropy collection loop in jent_gen_entropy checks for
the health test failure upon each loop iteration. However, the
initialization operation checked for the APT health test once for
an APT window which implies it would not catch most errors.
Thus, the check for all health errors is now invoked unconditionally
during each loop iteration for the startup test.
With the change, the error JENT_ERCT becomes unused as all health
errors are only reported with the JENT_HEALTH return code. This
allows the removal of the error indicator.

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.
