Hi Huisong,
I knew that this patchset was based on the *dpdk-next-net* repository
in our previous communication. However, maybe it's better to rebase
this pactchset on the *dpdk* repository. Because the CI system is not
smart enough to recognize the patchset as a change for the
*dpdk-next-net* repository. I personally feel this patchset is more
likely a change for the *dpdk* repository because it modified the
`lib` directory which is the infrastructure of DPDK instead of a
feature for *dpdk-next-net*.
Generally, the 'dpdk-next-net' repo is ahead of 'dpdk' repo. And we make
some development based on 'dpdk-next-net' repo.
I found that there are some patches also happen to the same issue that
CI applt patch failed.
So I think the reason why this series trigger warning should be analyzed
and resolved.

And the "/sys/devices/system/cpu/cpuX/power/pm_qos_resume_latency_us"
sysfs
interface is used to set and get the resume latency limit on the cpuX
for
userspace. Each cpuidle governor in Linux select which idle state to
enter
based on this CPU resume latency in their idle task.
The per-CPU PM QoS API can be used to control this CPU's idle state
selection and limit just enter the shallowest idle state to low the
delay
after sleep by setting strict resume latency (zero value).
