Symbols/Function Pointers: %pF versatile_init+0x0/0x110 %pf versatile_init %pS versatile_init+0x0/0x110 %pSR versatile_init+0x9/0x110 (with __builtin_extract_return_addr() translation) %ps versatile_init %pB prev_fn_of_versatile_init+0x88/0x88 For printing symbols and function pointers. The 'S' and 's' specifiers result in the symbol name with ('S') or without ('s') offsets. Where this is used on a kernel without KALLSYMS - the symbol address is printed instead. The 'B' specifier results in the symbol name with offsets and should be used when printing stack backtraces. The specifier takes into consideration the effect of compiler optimisations which may occur when tail-call's are used and marked with the noreturn GCC attribute. On ia64, ppc64 and parisc64 architectures function pointers are actually function descriptors which must first be resolved. The 'F' and 'f' specifiers perform this resolution and then provide the same functionality as the 'S' and 's' specifiers.
