46 - accounting anonymous pages, file caches, swap caches usage and limiting them.
48 - optionally, memory+swap usage can be accounted and limited.
71 memory.memsw.usage_in_bytes show current usage for memory+Swap
74 memory.memsw.limit_in_bytes set/show limit of memory+Swap usage
76 memory.memsw.failcnt show the number of memory+Swap hits limits
78 memory.memsw.max_usage_in_bytes show max memory+Swap usage recorded
215 Since page's memcg recorded into swap whatever memsw enabled, the page will
236 2.4 Swap Extension
239 Swap usage is always recorded for each of cgroup. Swap Extension allows you to
247 memsw means memory+swap. Usage of memory+swap is limited by
250 Example: Assume a system with 4G of swap. A task which allocates 6G of memory
251 (by mistake) under 2G memory limitation will use all swap.
252 In this case, setting memsw.limit_in_bytes=3G will prevent bad use of swap.
253 By using the memsw limit, you can avoid system OOM which can be caused by swap
256 2.4.1 why 'memory+swap' rather than swap
259 The global LRU(kswapd) can swap out arbitrary pages. Swap-out means
260 to move account from memory to swap...there is no change in usage of
261 memory+swap. In other words, when we want to limit the usage of swap without
262 affecting global LRU, memory+swap limit is better than just limiting swap from
268 When a cgroup hits memory.memsw.limit_in_bytes, it's useless to do swap-out
269 in this cgroup. Then, swap-out will not be done by cgroup routine and file
479 2. The user is using anonymous memory and swap is turned off or too low
513 Charges recorded in swap information is not updated at removal of cgroup.
514 Recorded information is discarded and a cgroup which uses swap (swapcache)
