I need a little help from Masami Hiramatsu to understand what the plan is here: Do we just need to remove those files now that jprobes are gone, or do we actually want to restore the functionality using some other replacement code?
I'm asking because the __deprecated warning seems unhelpful if there isn't an easy way to address the warning.
It seems that the arm/probes case is just for testing, I'll just remove it because it's functionality is gone.
Makes sense, thanks!
Others should be decided by network maintainers. Maybe those are not used anymore, or should be rewritten by kprobes or ftrace.
Added a few people to cc that worked on {tcp,dccp,sctp}_probe in the past for clarification. Do you already have plans to deal with this?
