Help text

Add .low limit interface for block throttling. The low limit is a best effort limit to prioritize cgroups. Depending on the setting, the limit can be used to protect cgroups in terms of bandwidth/iops and better utilize disk resource.

Note, this is an experimental interface and could be changed someday.
