Shouldn't sgx_can_reclaim() also take a 'struct sgx_epc_lru_lists *'?
I thought we also need to check whether a cgroup's LRU lists can be
reclaimed?
This is only used to check if any pages reclaimable at the top level in
this file. Later sgx_epc_cgroup_lru_empty(NULL) is used in this function
to recursively check all cgroups starting from the root.
