There is no object size change with is_ereg() defined "static inline" or "static" Curiously, if you mark it noinline, the size increases. gcc 4.9.1, x86-64, -O2 no profiling support $ size arch/x86/net/bpf_jit_comp.o.st* text data bss dec hex filename 10679 4 0 10683 29bb arch/x86/net/bpf_jit_comp.o.static_inline 11535 4 0 11539 2d13 arch/x86/net/bpf_jit_comp.o.static_noinline 10679 4 0 10683 29bb arch/x86/net/bpf_jit_comp.o.static_without_inline -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
