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 private LRU. Now, its handling is under global
138 Almost all routines around memcg's LRU is called by global LRU's
142 memcg's private LRU and call __isolate_lru_page() to extract a page
154 9.1 Small limit to memcg.
157 When you do test to do racy case, it's good test to set memcg's limit
167 Historically, memcg's shmem handling was poor and we saw some amount
