From 8461ef8b7ef286212ca954d8b82dac3ceecb219d Mon Sep 17 00:00:00 2001 From: Yonghong Song Date: Fri, 1 Feb 2019 16:14:14 -0800 Subject: tools/bpf: move libbpf pr_* debug print functions to headers A global function libbpf_print, which is invisible outside the shared library, is defined to print based on levels. The pr_warning, pr_info and pr_debug macros are moved into the newly created header common.h. So any .c file including common.h can use these macros directly. Currently btf__new and btf_ext__new API has an argument getting __pr_debug function pointer into btf.c so the debugging information can be printed there. This patch removed this parameter from btf__new and btf_ext__new and directly using pr_debug in btf.c. Another global function libbpf_print_level_available, also invisible outside the shared library, can test whether a particular level debug printing is available or not. It is used in btf.c to test whether DEBUG level debug printing is availabl or not, based on which the log buffer will be allocated when loading btf to the kernel.
