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
228 Since page's memcg recorded into swap whatever memsw enabled, the page will
245 2.4 Swap Extension
248 Swap usage is always recorded for each of cgroup. Swap Extension allows you to
256 memsw means memory+swap. Usage of memory+swap is limited by
259 Example: Assume a system with 4G of swap. A task which allocates 6G of memory
260 (by mistake) under 2G memory limitation will use all swap.
261 In this case, setting memsw.limit_in_bytes=3G will prevent bad use of swap.
262 By using the memsw limit, you can avoid system OOM which can be caused by swap
265 2.4.1 why 'memory+swap' rather than swap
268 The global LRU(kswapd) can swap out arbitrary pages. Swap-out means
269 to move account from memory to swap...there is no change in usage of
270 memory+swap. In other words, when we want to limit the usage of swap without
271 affecting global LRU, memory+swap limit is better than just limiting swap from
277 When a cgroup hits memory.memsw.limit_in_bytes, it's useless to do swap-out
278 in this cgroup. Then, swap-out will not be done by cgroup routine and file
488 2. The user is using anonymous memory and swap is turned off or too low
522 Charges recorded in swap information is not updated at removal of cgroup.
523 Recorded information is discarded and a cgroup which uses swap (swapcache)
552 rss # of bytes of anonymous and swap cache memory (includes

629 there is a swap storage available. This might lead to memcg OOM killer
649 method and doesn't show 'exact' value of memory (and swap) usage, it's a fuzz
651 If you want to know more exact memory usage, you should use RSS+CACHE(+SWAP)
849 pressure, the system might be making swap, paging out active file caches,
