From: Kristen Carlson Accardi
Previous patches have implemented all infrastructure needed for
per-cgroup EPC page tracking and reclaiming. But all reclaimable EPC
pages are still tracked in the global LRU as sgx_lru_list() returns hard
coded reference to the global LRU.
Change sgx_lru_list() to
5 matches
