In previous patch, we have created an evsel_streams for one event,

We show the streams separately. They are divided into different sections.
1. "Matched hot streams"
2. "Hot streams in old perf data only"
3. "Hot streams in new perf data only".
For each stream, we report the cycles and hot percent (hits%).
For example,
cycles: 2, hits: 4.08%
Sometimes, a small change in a hot function reducing the cycles of
this function, but the overall workload doesn't get faster. It is
interesting where the cycles are moved to.

We have used callchain_node->hit to measure the hot level of one

When napi_consume_skb() is called in the tx desc cleaning process,
it is usually in the softirq context(BH disabled, or are processing
softirqs), but it may also be in the task context, such as in the
netpoll or loopback selftest process.
Currently napi_consume_skb() uses non-zero budget to
A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "devm_kcalloc".

Currently, rcu_do_batch() depends on the unsegmented callback list's len field
to know how many CBs are executed. This fields counts down from 0 as CBs are

limits in which case the remaining unexecuted callbacks are

This patch is split up because I'm not sure about the patch, and also because
it does not fix the issue I am seeing with TREE04. :-(. Though it does fix the
theoretical issue I was considering, with rcu_barrier.
The previous patch breaks rcu_barrier (in theory at least). This is because
Track how the segcb list changes before/after acceleration, during
queuing and during dequeuing.
This has proved useful to discover an optimization to avoid unwanted GP
requests when there are no callbacks accelerated. The overhead is minimal as
each segment's length is now stored in the
Add counting of segment lengths of segmented callback list.
This will be useful for a number of things such as knowing how big the
ready-to-execute segment have gotten. The immediate benefit is ability
to trace how the callbacks in the segmented callback list change.
