Re: [Y2038] [PATCH 20/24] compat_ioctl: move HDIO ioctl handling into drivers/ide

+static int put_user_long(long val, unsigned long arg) +{ +#ifdef CONFIG_COMPAT

• if (in_compat_syscall())

• return put_user(val, (compat_long_t __user *)compat_ptr(arg));
  

+#endif

• return put_user(val, (long __user *)arg);

+}

We had this

#ifdef CONFIG_COMPAT if (in_compat_syscall()) ... ... #endif

patter quite frequently. Can we define a in_compat_syscall stub and make sure compat_ptr and the compat_* types are available available to clean this up a bit?

• if (NULL == (void *) arg) {

• if (NULL == argp) {

if (!argp) {

?
