I understand where you are coming from with these.
But what I see now is:

ENTRY/END
PROC/ENDPROC
KPROBE_ENTRY/KPROBE_END

And it is not obvious for me reading the comment when I should
expect which one to be used.

Could we try to keep it down to two variants?
And then document when to use which one.
