From ed8b4c90ea92f67e245b84441a539070b482f56a Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Fri, 20 Jan 2023 12:08:59 -0800 Subject: [PATCH] libbpf: Add BPF_UPROBE and BPF_URETPROBE macro aliases Add BPF_UPROBE and BPF_URETPROBE macros, aliased to BPF_KPROBE and BPF_KRETPROBE, respectively. This makes uprobe-based BPF program code much less confusing, especially to people new to tracing, at no cost in terms of maintainability. We'll use this macro in selftests in subsequent patch.
