41  - accounting anonymous pages, file caches, swap caches usage and limiting them.
43  - optionally, memory+swap usage can be accounted and limited.
186 causing page fault. So, we avoid accounting at swap-in I/O.
211 Swap Extension allows you to record charge for swap. A swapped-in page is
214 When swap is accounted, following files are added.
218 memsw means memory+swap. Usage of memory+swap is limited by
221 Example: Assume a system with 4G of swap. A task which allocates 6G of memory
222 (by mistake) under 2G memory limitation will use all swap.
223 In this case, setting memsw.limit_in_bytes=3G will prevent bad use of swap.
224 By using the memsw limit, you can avoid system OOM which can be caused by swap
227 * why 'memory+swap' rather than swap.
228 The global LRU(kswapd) can swap out arbitrary pages. Swap-out means
229 to move account from memory to swap...there is no change in usage of
230 memory+swap. In other words, when we want to limit the usage of swap without
231 affecting global LRU, memory+swap limit is better than just limiting swap from
235 When a cgroup hits memory.memsw.limit_in_bytes, it's useless to do swap-out
236 in this cgroup. Then, swap-out will not be done by cgroup routine and file
359 c. Enable CONFIG_MEMCG_SWAP (to use swap extension)

546 there is a swap storage available. This might lead to memcg OOM killer
