If you unconditionally define sched_info_on(), you can get get rid of
this #ifdef.

+#if defined(CONFIG_SCHEDSTATS) || defined(CONFIG_TASK_DELAY_ACCT)
+
+static inline int sched_info_on(void)
+{
+ #ifdef CONFIG_SCHEDSTATS
+       return 1;
+#elif defined(CONFIG_TASK_DELAY_ACCT)
+       return delayacct_on;
+#else
+	return 0;
+#endif
+}

Might as well hide the junk in a header.
