Quoting Oren Laadan (orenl@xxxxxxxxxxxxxxx): > Checkpointing of multiple processes works by recording the tasks tree > structure below a given task (usually this task is the container init). > > For a given task, do a DFS scan of the tasks tree and collect them > into an array (keeping a reference to each task). Using DFS simplifies > the recreation of tasks either in user space or kernel space. For each > task collected, test if it can be checkpointed, and save its pid, tgid, > and ppid. > > The actual work is divided into two passes: a first scan counts the > tasks, then memory is allocated and a second scan fills the array. > > The logic is suitable for creation of processes during restart either > in userspace or by the kernel. > > Currently we ignore threads and zombies, as well as session ids. > > Signed-off-by: Oren Laadan <orenl@xxxxxxxxxxxxxxx> Looks good.
