This field reports swap-only usage. For cgroupv1, `Usage` and `Failcnt` are set by subtracting memory usage from memory+swap usage. For cgroupv2, `Usage`, `Limit`, and `MaxUsage` are set. This commit also export `MaxUsage` of memory under cgroupv2 mode, using `memory.peak` introduced in kernel 5.19.
