[PATCH 01/10] enable cgroup cpuset by default

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This prepares for subsequent patches which introduce dependence
on cgroup cpuset. Enable cgroup cpuset by default so users don't
have to modify configuration file before encountering a cpuset
error.
