-+
-+## Swap handling
-+If you noticed LXCFS not showing any SWAP in your container despite
-+having SWAP on your system, please read this section carefully and look
-+for instructions on how to enable SWAP accounting for your distribution.
-+
-+Swap cgroup handling on Linux is very confusing and there just isn't a
-+perfect way for LXCFS to handle it.
-+
-+Terminology used below:
-+ - RAM refers to `memory.usage_in_bytes` and `memory.limit_in_bytes`
-+ - RAM+SWAP refers to `memory.memsw.usage_in_bytes` and `memory.memsw.limit_in_bytes`
-+
-+The main issues are:
-+ - SWAP accounting is often opt-in and, requiring a special kernel boot
-+   time option (`swapaccount=1`) and/or special kernel build options
-+   (`CONFIG_MEMCG_SWAP`).
-+
-+ - Both a RAM limit and a RAM+SWAP limit can be set. The delta however
-+   isn't the available SWAP space as the kernel is still free to SWAP as
-+   much of the RAM as it feels like. This makes it impossible to render
-+   a SWAP device size as using the delta between RAM and RAM+SWAP for that
-+   wouldn't account for the kernel swapping more pages, leading to swap
-+   usage exceeding swap total.
-+
-+ - It's impossible to disable SWAP in a given container. The closest
-+   that can be done is setting swappiness down to 0 which severly limits
-+   the risk of swapping pages but doesn't eliminate it.
-+
-+As a result, LXCFS had to make some compromise which go as follow:
-+ - When SWAP accounting isn't enabled, no SWAP space is reported at all.
-+   This is simply because there is no way to know the SWAP consumption.
-+   The container may very much be using some SWAP though, there's just
-+   no way to know how much of it and showing a SWAP device would require
-+   some kind of SWAP usage to be reported. Showing the host value would be
-+   completely wrong, showing a 0 value would be equallty wrong.
-+
-+ - Because SWAP usage for a given container can exceed the delta between
-+   RAM and RAM+SWAP, the SWAP size is always reported to be the smaller of
-+   the RAM+SWAP limit or the host SWAP device itself. This ensures that at no
-+   point SWAP usage will be allowed to exceed the SWAP size.
-+
-+ - If the swappiness is set to 0 and there is no SWAP usage, no SWAP is reported.
-+   However if there is SWAP usage, then a SWAP device of the size of the
-+   usage (100% full) is reported. This provides adequate reporting of
-+   the memory consumption while preventing applications from assuming more
-+   SWAP is available.
