10 is complex. This is a document for memcg's internal behavior.
61 At commit(), the page is associated with the memcg.
114 But brief explanation of the behavior of memcg around shmem will be
136 Each memcg has its own vector of LRUs (inactive anon, active anon,
138 each LRU handled under a single lru_lock for that memcg and node.
145 9.1 Small limit to memcg.
148 When you do test to do racy case, it's good test to set memcg's limit
158 Historically, memcg's shmem handling was poor and we saw some amount
