------- Comment From praveen.pan...@in.ibm.com 2018-03-19 02:22 EDT------- Hi canonical,
I ran stress-ng and i did not see any issue in system and idea is to change this default setting to always as by default user able to use thp functionality if some workload has issue on this than it can be disabled by user .
