Conversation
The tasksInsidePodCgroup function was hardcoded to use the 'memory' subsystem path which only works with cgroup v1. This commit adds support for cgroup v2: 1. Add cgroupV2Mode flag and isCgroupV2() function to detect cgroup version 2. In cgroup v2 mode, use correct path without 'memory' subsystem 3. In cgroup v2 mode, use 'cgroup.threads' instead of 'tasks' file 4. Also update getSandboxPID function to use correct tasks file name Fixes alibaba#348
