- Fix memory limit detection logic for cgroup v1: treat 0x7FFFFFFFFFFFF000 (9223372036854771712) as unlimited. - Ensure cgroup v2 uses "max" as unlimited. - Update comments to English for better readability. - This ensures memory stress respects container memory limits correctly. Signed-off-by: xiejunqiao <xiejunqiao@wps.cn>
- Change exec.Command("memStress", ...) to exec.Command("./memStress", ...)
- This avoids "executable file not found in $PATH" error when current directory is not in $PATH
- No impact on other features
