tcp_dsack - BOOLEAN
Allows TCP to send "duplicate" SACKs.

Enable Explicit Congestion Notification (ECN) in TCP. ECN is only
used when both ends of the TCP flow support it. It is useful to
avoid losses due to congestion (when the bottleneck router supports
+Version 15 of schedstats dropped counters for some sched_yield:
+yld_exp_empty, yld_act_empty and yld_both_empty. Otherwise, it is
+identical to version 14.

Version 14 of schedstats includes support for sched_domains, which hit the
mainline kernel in 2.6.20 although it is identical to the stats from version
12 which was in the kernel from 2.6.13-2.6.19 (version 13 never saw a kernel

-NOTE: In the sched_yield() statistics, the active queue is considered empty
- if it has only one process in it, since obviously the process calling
- sched_yield() is that process.
+cpu<N> 1 2 3 4 5 6 7 8 9
-First four fields are sched_yield() statistics:
- 1) # of times both the active and the expired queue were empty

- 3) # of times just the expired queue was empty
- 4) # of times sched_yield() was called
+First field is a sched_yield() statistic:
+ 1) # of times sched_yield() was called
Next three are schedule() statistics:
- 5) # of times we switched to the expired queue and reused it
- 6) # of times schedule() was called
- 7) # of times schedule() left the processor idle
+ 2) # of times we switched to the expired queue and reused it
+ 3) # of times schedule() was called

+ 5) # of times try_to_wake_up() was called
+ 6) # of times try_to_wake_up() was called to wake up the local cpu
Next three are statistics describing scheduling latency:
