Add myself as Memory's maintainer - Cloud Kernel

23 Sep 2022

Hi,  All

I've been working on linux kernel memory over the past few years,   
making some

contributions in the field and alway helping review the related code.

Here are some highlight contributions from myself:

1、Implement the cold slab design and development.  It aims to reclaim 
the kernel slab memory to

      reduce the unexpected stability issues and saving some memory 
space.  The feautre has widely

      applied to alibaba group.

2、Implement the swap high feature in cgroup v1 and make use of oomd to 
proactive kill in the process

      rather than trigger the Oom killer in the kernel,  which aims to 
decrease the risk of unexpected hang

      or Oom.  hence the user can control  when to kill and what process 
to kill.

      The ability has been applied to ASI control components.

3、 Design and implement the  performance optimization to reduce the cost 
for redis snapshot.

       The performance benifits is that the whole cost from second to 
millisecond.

4、Design and implement the dup page in the early stage.  It's proved 
that has a great improvments when

      the app  will access the remote binary program frequently.

5、Backport mglru feature to make the page to identify the cold and hot 
and implement proactiving the anonymous page with

     zswap and file page to reclaim within the reasonable refault value.

     Flink has take use of the alibity in the product environment to 
achieve the goals of saving the memory about at least 5% only

     in page cache.

With the above key contributions,  I think I am qualified with the job.  
Thanks
