46 - accounting anonymous pages, file caches, swap caches usage and limiting them.
48 - optionally, memory+swap usage can be accounted and limited.
69 memory.memsw.usage_in_bytes show current usage for memory+Swap
72 memory.memsw.limit_in_bytes set/show limit of memory+Swap usage
74 memory.memsw.failcnt show the number of memory+Swap hits limits
76 memory.memsw.max_usage_in_bytes show max memory+Swap usage recorded
205 Since page's memcg recorded into swap whatever memsw enabled, the page will
225 2.4 Swap Extension
228 Swap usage is always recorded for each of cgroup. Swap Extension allows you to
236 memsw means memory+swap. Usage of memory+swap is limited by
239 Example: Assume a system with 4G of swap. A task which allocates 6G of memory
240 (by mistake) under 2G memory limitation will use all swap.
241 In this case, setting memsw.limit_in_bytes=3G will prevent bad use of swap.
242 By using the memsw limit, you can avoid system OOM which can be caused by swap
245 **why 'memory+swap' rather than swap**
247 The global LRU(kswapd) can swap out arbitrary pages. Swap-out means
248 to move account from memory to swap...there is no change in usage of
249 memory+swap. In other words, when we want to limit the usage of swap without
250 affecting global LRU, memory+swap limit is better than just limiting swap from
255 When a cgroup hits memory.memsw.limit_in_bytes, it's useless to do swap-out
256 in this cgroup. Then, swap-out will not be done by cgroup routine and file
390 c. Enable CONFIG_MEMCG_SWAP (to use swap extension)
