I couldn't figure out why this failure you have encountered. I think
OpenSUSE kernel most likely config CGROUP_MISC.
Also if CGROUP_MISC not set, then there should be error happen earlier on
echoing "+misc" to cgroup.subtree_control at line 20. But your log
indicates only error on echoing "sgx_epc ..." to
/sys/fs/cgroup/...//misc.max.
I can only speculate that can could happen (if sgx epc cgroup was compiled
in) when the cgroup-fs subdirectories in question already have populated
config that is conflicting with the scripts.
Could you double check or start from a clean environment?
Thanks
Haitao
