--- Patch [1]: [PATCH v3 1/1] Documentation: real-time: Add kernel configuration guide ---
commit aafa57307e83d54cf2bd4f383aa2ee5d683dab92
Author: Ahmed S. Darwish <darwi@linutronix.de>

Documentation: real-time: Add kernel configuration guide

This commit adds a configuration guide for real-time kernels. It lists
Kconfig options that are recommended to be either enabled or disabled to
help manage worst-case latency.

[Severity: Low]
Does CONFIG_WQ_SYSFS exist? Searching the Kconfig files doesn't show
this option. Could this be confusing the WQ_SYSFS allocation flag used in
the C code with a kernel configuration option?

[Severity: Low]
This isn't a bug, but this hyperlink target is defined here and never
referenced in the rest of the document. Will this cause the link to be
invisible in the generated HTML documentation?
