Minor bug fixes for the group scheduler: - Use a mutex to serialize add/remove of task groups and also when changing shares of a task group. Use the same mutex when printing cfs_rq debugging stats for various task groups. - Use list_for_each_entry_rcu in for_each_leaf_cfs_rq macro (when walking task group list) Signed-off-by: NSrivatsa Vaddagiri <vatsa@linux.vnet.ibm.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
