kdb: kdb_support: Fix debugging information problem
There are several common patterns. 0: kdb_printf("...",...); which is the normal one. 1: kdb_printf("%s: "...,__func__,...) We could improve '1' to this : #define kdb_func_printf(format, args...) \ kdb_printf("%s: " format, __func__, ## args) 2: if(KDB_DEBUG(AR)) kdb_printf("%s "...,__func__,...); We could improve '2' to this : #define kdb_dbg_printf(mask, format, args...) \ do { \ if (KDB_DEBUG(mask)) \ kdb_func_printf(format, ## args); \ } while (0) In addition, we changed the format code of size_t to %zu.
