A value of "default" in memory.swapfile indicates that this cgroup should use the default, system-wide, swap files. A value of "none" indicates that this cgroup should never swap. Other values are interpreted as the path to a private swap file that can only be used by the owner (and its children). The swap file has to be created and swapon() has to be done on it with SWAP_FLAG_PRIVATE, before it can be used. This flag ensures that the swap file is private and does not get used by others. Jamie Liu (1): swap: do not store private swap files on swap_list Suleiman Souhlal (2): mm/swap: support per memory cgroup swapfiles swap: Increase the maximum number of swap files to 8192.
