| |
Since these fmt_* variables are just const char*, and not const char[], gcc (and smatch) doesn't to type checking of the arguments to the printf functions. Since the linker knows perfectly well to merge identical string constants, there's no point in having three static pointers waste memory and give an extra level of indirection.
This removes over 100 "non-constant format argument" warnings from smatch, accounting for about 20% of all such warnings in an allmodconfig.
