try #undef pr_fmt #define pr_fmt(fmt) "%s.c:%d: %s " fmt, __FILE__, __LINE__, __func__ On Tue, 3 Aug 2021 at 21:44, <jim.cromie@gmail.com> wrote:
hi all,
there are many uses of : pr_debug("%s ...\n", __func__, ...)
I tried to do a preprocessor catenation to replace the runtime work, but that falls afoul of the def.
from gnu gcc web-page:
The identifier __func__ is implicitly declared by the translator as if, immediately following the opening brace of each function definition, the declaration
static const char __func__[] = "function-name";
These identifiers are variables, not preprocessor macros, and may not be used to initialize char arrays or be concatenated with string literals.
is there a kernel macro version that would allow this "optimization" ?
