Revision 2cc78eb52bc1ae89f0a4fa5a00eb998dffde4a9f authored by Linus Torvalds on 17 October 2005, 16:10:15 UTC, committed by Linus Torvalds on 17 October 2005, 16:10:15 UTC 
Increase default RCU batching sharply
 
Dipankar made RCU limit the batch size to improve latency, but that
approach is unworkable: it can cause the RCU queues to grow without
bounds, since the batch limiter ended up limiting the callbacks.

So make the limit much higher, and start planning on instead limiting
the batch size by doing RCU callbacks more often if the queue looks like
it might be growing too long.
