From 307ef667e94530c2f2f77797bfe9ea85c22bec7d Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Thu, 20 Mar 2025 15:24:39 -0700 Subject: libbpf: Add namespace for errstr making it libbpf_errstr When statically linking symbols can be replaced with those from other statically linked libraries depending on the link order and the hoped for "multiple definition" error may not appear. To avoid conflicts it is good practice to namespace symbols, this change renames errstr to libbpf_errstr. To avoid churn a #define is used to turn use of errstr(err) to libbpf_errstr(err).
