Thanks!
I didn't add you to Cc list since [PATCH 2/2] is architecture specific. According to the feedbacks, it is needed to figure out fundamental solutions: 1) reduce stack size and 2) focus on a generic anti-fragmentation logic.
Please refer to https://lkml.org/lkml/2015/5/24/121 for [PATCH 2/2].
Best Regards Jungseok Lee
