Struct RdmaController

Source 
pub struct RdmaController { /* private fields */ }
Expand description

A controller that allows controlling the rdma subsystem of a Cgroup.

In essence, using this controller one can limit the RDMA/IB specific resources that the tasks in the control group can use.

Implementations§

Source

pub fn current(&self) -> Result<String>

Returns the current usage of RDMA/IB specific resources.

Source

pub fn set_max(&self, max: &str) -> Result<()>
