Can cgroup memory subsystem provide estimated available memory, just like /proc/meminfo: MemAvailable?

["王欢(云痕)" <huan.wanghuan@xxxxxxxxxxxxxxx>]

Hello cgroup & memory experts,

/proc/meminfo: MemAvailable is a very useful mertics that provides estimated available memory,  calculated by MemFree, Active(file), Inactive(file), SReclaimable and Watermarks. It is implemented by the si_mem_available() function. Can cgroup memory subsystem provide estimated available memory?

/proc/meminfo:

MemTotal:       63793888 kB

MemFree:        21124704 kB
