Hello cgroup experts,

/proc/meminfo: MemAvailable is a very useful mertics, provide estimated available memory, caculated by MemFree, Active(file), Inactive(file), SReclaimable and watermarks. It is implemented by the si_mem_available() function[1]. Can cgroup memory subsystem provide estimated available memory?

/proc/meminfo:

MemTotal:       63793888 kB

MemFree:        21124704 kB

MemAvailable:   39106088 kB
