Eprobes was added back in 5.15, but was never documented. It became a "secret" interface even though it has been a topic of several presentations. For some reason, when eprobes was added, documenting it never became a priority, until now.

Linux Tracing Technologies Guide
|
|
================================
|
|
|
|
Tracing in the Linux kernel is a powerful mechanism that allows
|
|
developers and system administrators to analyze and debug system
|
|
behavior. This guide provides documentation on various tracing
|
|
frameworks and tools available in the Linux kernel.
|
|
|
|
Introduction to Tracing
