When to use the gproc project patch files?

Question

While studying the source files of the gproc project, I found several patch files in the patch directory (for example, kernel.erl, gen_event.erl, gen_fsm.erl, gen.erl, supervisor.erl, sys. Earl). But the readme and makefile do not say anything about these files.

Since the erlang runtime version has been updated frequently, and now my machine uses R15B. Could you tell me if I need to fix the runtime? If possible, please give me a little explanation.

Answer 1

Patches exist only to demonstrate how the application could work if it were an integrated Erlang / OTP component, so you do not need (or need, perhaps) to apply them.
