Hi Dave,
I was getting the following error upon executing "runq -g".
runq: invalid structure member offset: cfs_rq_throttled
FILE: task.c LINE: 7615 FUNCTION: print_group_header_fair()
[./crash] error trace: 80e98b0 => 80e9815 => 80e577f => 8143bde
TASK_GROUP: dac06c80 CFS_RQ: dac06080 <apps>runq: input string
too large: "000000000808ec50" (16 vs 8)
"cfs_bandwidth" is available in task_group irrespective of whether
CONFIG_CFS_BANDWIDTH is enabled or not (but empty). But "throttled" is
available in cfs_rq only if config is enabled. The following patch
fixes this.

Thanks,
