Linux 实时抢占

digdeep126

在man sched_setscheduler中看到：
From  kernel version 2.6.18 onwards, however, Linux is gradually becoming equipped with real-time capabilities, most  of  which  are  derived from  the  former  realtime-preempt  patches  developed by Ingo Molnar,
       Thomas Gleixner, Steven Rostedt, and others.  Until  the  patches  have been completely merged into the mainline kernel (this is expected to be around kernel version 2.6.30), they must be installed  to  achieve  the  best real-time performance.
请问各位大牛：现在（2.6.38-8）Linux的实时抢占部分的patches是否已经被融入了内核，也就是现在不用手动打patch了? 谢谢！
