I am Kunwu.Chan（Chinese name is "陈涛"，courtesy name is "昆吾"）, a Linux kernel developer.
I also collaborated with Barry Song on multiple memory management research topics, including the optimization of per-VMA locks 1 2 3.
This body of work laid solid technical groundwork for his presentation 'Optimising major page faults' delivered at this year’s LSF (Linux Storage, Filesystem & Memory Management Summit).
We also tackled high-order memory allocation issues under network workloads 4 5.
From 2023 to 2024, my main contributions centered on memory safety vulnerability mitigation. I adopted a proactive preemption approach to block vulnerabilities before they could be exploited. For instance, flaws tracked under CVE-2023-52675, CVE-2023-52607, CVE-2023-52686, CVE-2024-35940, CVE-2024-35943 and CVE-2024-26771 were all patched prior to public disclosure.
Within a single year, my work was featured three times on Kylin Software’s official WeChat public account:
Linux 6.9版本内核贡献数量领先！他们来自麒麟软件
2024 Linux kernel补丁贡献量出炉：麒麟软件在中国企业名列前茅
对话Linux之父！麒麟软件代表参加内核顶会
- Number of contributions: About 100+ 6
- RCU: My previous technical analysisObservations on KVM SRCU Grace-Period Latency has been included in the officialLinux-Kernel RCU Design Documents by Paul E. McKenney, the father of RCU.
Broad-ranging, always maintaining curiosity and desire to explore technology
In the past ten years, the kernel has involved RCU, virtualization, memory security and other fields
Stay hungry in kernel technology, take one step at a time, and work hard for a long time
Hiking:
- The highest mountain I’ve climbed: Mount Siguniang’s Second Peak (5,270 meters above sea level)
- I have traveled from south to north. When I am bored, I like to go to the mountains alone. Heavy camping and drinking tea by the river are all OK
- I went to Tiger Leaping Gorge in Yunnan in 2023, saw the narrowest part of the Yangtze River. Along the river, the majestic Haba Snow Mountain stands to the left, while the splendid Thirteen Peaks of Jade Dragon Snow Mountain can be admired to the right, with the relentless rush of the Jinsha River flowing beneath. When I climbed the 168-meter ladder using my hands and feet, I felt that my fear of heights was improved a little. The profile picture I’m using now was taken on the mountain on the Tiger Leaping Gorge Highway. I was facing the Jade Dragon Snow Mountain.
- During the May Day holiday in 2023, I completed a 100km hiking trip on Hong Kong’s MacLehose Trail while carrying tent supplies and camping.
- Professional ability: "Primary Mountain Outdoor Instructor" of China Mountaineering Association, "Level 3 Mountain Outdoor Athlete" of China Mountaineering Association, and Mountain Eagle One-Star Outdoor Leader
Cycling:
- In summer and autumn, I like to ride shared bicycles from Changsha to Xiangtan and back
Marathon
- I recently started running and completed my first half marathon in March 2025 and will be running my second half marathon in April.
