Common operations of all cgroups.

Required Methods

fn id(&self) -> u64

Returns the unique ID of the cgroup. ID of root cgroup is 0.

fn add_process( &self, locked: &mut Locked<FileOpsCore>, thread_group: &ThreadGroup, ) -> Result<(), Errno>

Add a process to a cgroup. Errors if the cgroup has been deleted.

fn new_child(&self, name: &FsStr) -> Result<CgroupHandle, Errno>

Create a new sub-cgroup as a child of this cgroup. Errors if the cgroup is deleted, or a child with name already exists.

fn get_children(&self) -> Result<Vec<CgroupHandle>, Errno>

Gets all children of this cgroup.

fn get_child(&self, name: &FsStr) -> Result<CgroupHandle, Errno>

Gets the child with name, errors if not found.

fn remove_child(&self, name: &FsStr) -> Result<CgroupHandle, Errno>

Remove a child from this cgroup and return it, if found. Errors if cgroup is deleted, or a child with name is not found.

fn get_pids(&self, kernel: &Kernel) -> Vec<pid_t>

Return all pids that belong to this cgroup.

fn kill(&self)

Kills all processes in the cgroup and its descendants.

fn is_populated(&self) -> bool

Whether the cgroup or any of its descendants have any processes.

fn get_freezer_state(&self) -> CgroupFreezerState

Get the freezer self state and effective state.

fn freeze(&self, locked: &mut Locked<FileOpsCore>)

Freeze all tasks in the cgroup.

fn thaw(&self)

Thaw all tasks in the cgroup.
