Correct - but we can rewrite it like this: diff --git a/include/linux/acct.h b/include/linux/acct.h index 882dc72..bcc6d2f 100644 --- a/include/linux/acct.h +++ b/include/linux/acct.h @@ -59,8 +59,12 @@ struct acct comp_t ac_majflt; /* Major Pagefaults */ comp_t ac_swaps; /* Number of Swaps */ /* m68k had no padding here. */ -#if !defined(CONFIG_M68K) || !defined(__KERNEL__) +#ifndef __KERNEL__ __u16 ac_ahz; /* AHZ */ +#else + #ifndef CONFIG_M68K + __u16 ac_ahz; /* AHZ */ + #endif #endif __u32 ac_exitcode; /* Exitcode */ char ac_comm[ACCT_COMM + 1]; /* Command Name */ This is at least for me also easier to parse. So we remove a (bogus) warning and make the code easier to read. Sam
