[PATCH 2/3] Reset nr_balance_failed after active balancing

. Resetting the nr_balance_failed after a successful active balance, ensures that a hot task is not unreasonably migrated. This can be verified by looking at number of hot task migrations reported by /proc/schedstat. Signed-off-by: Srikar Dronamraju <sri...@linux.vnet.ibm.com> --- kernel/sched/fair.

[PATCH 1/3] sched: Move print_cfs_rq declaration to kernel/sched/sched.h

Currently print_cfs_rq() is declared in include/linux/sched.h. However its not used outside kernel/sched. Hence move the declaration to kernel/sched/sched.h Also some functions are only available for CONFIG_SCHED_DEBUG. Hence move the declarations within #ifdef. Signed-off-by: Srikar Dronamraju
