pub fn cgroup_max_tasks() -> Option<usize>Expand description
Returns the cgroup task-count limit applying to this process.
Container runtimes impose a task ceiling through the cgroup v2 pids
controller, which RLIMIT_NPROC does not reflect: Podman defaults to 2,048
tasks while leaving the rlimit unbounded. The effective ceiling is the
lowest limit set anywhere in the cgroup’s ancestry, so every ancestor is
read; None means none of them sets one, which also covers a cgroup v1
hierarchy.
