From 86f4b7f2578f69284fa782be54e700c42c757897 Mon Sep 17 00:00:00 2001 From: Quentin Monnet Date: Thu, 29 Jul 2021 17:20:25 +0100 Subject: tools: Replace btf__get_from_id() with btf__load_from_kernel_by_id() Replace the calls to function btf__get_from_id(), which we plan to deprecate before the library reaches v1.0, with calls to btf__load_from_kernel_by_id() in tools/ (bpftool, perf, selftests). Update the surrounding code accordingly (instead of passing a pointer to the btf struct, get it as a return value from the function).
