Use SPDX header for license Drop the lengthy license from each file and just use SPDX like most projects nowadays. This doesn't have any change to license, just how they are recorded in each file. This follows the kernel approach: header files use '/*' for comments while .c files use '//'. For .m4, use "#".

Add format attribute and fix issues Add __attribute__((format)) to log_filep() and _show() functions, fixing the bugs they found in the source code. For functions that receive va_list instead of being variadic functions we put 0 in the last argument, so at least the string is checked and we get warnings of -Wformat-nonliteral type. So, it's better than adding a pragma here to shut up the warning. 2013-04-22 03:16:18 +08:00			`void log_printf(int prio, const char *fmt, ...) _printf_format_(2, 3);`

tools: share setting up libkmod log This also fixes a bug in "e6996c5 rmmod: route all messages to syslog if told to" in which "+ verbose" was removed. Instead of letting verbose add to kmod_get_log_priority(), let it be similar to the other programs instead. 2012-11-07 04:26:34 +08:00			`struct kmod_ctx;`
