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
