"SwapPss" shows proportional swap share of this mapping. Unlike "Swap", this
does not take into account swapped out page of underlying shmem objects.
"Locked" indicates whether the mapping is locked in memory or not.
"THPeligible" indicates whether the mapping is eligible for THP pages - 1 if
true, 0 otherwise.
"VmFlags" field deserves a separate description. This member represents the kernel
