The goal is to make pr_* macros available to other C files than libbpf.c, and to simplify API function libbpf_set_print(). Specifically, Patch #1 used global functions to facilitate pr_* macros in the header files so they are available in different C files. Patch #2 removes the global function libbpf_dprint_level_available() which is added in Patch 1. Patch #3 simplified libbpf_set_print() which takes only one print function with a debug level argument among others. Changelogs: v2 -> v3: . bailed out earlier in libbpf_debug_print() if __libbpf_pr is NULL . added missing LIBBPF_DEBUG level check in libbpf.c __base_pr(). v1 -> v2: . Renamed global function libbpf_dprint() to libbpf_debug_print() to be more expressive. . Removed libbpf_dprint_level_available() as it is used only once in btf.c and we can remove it by optimizing for common cases.
