MemTotal: Total usable ram (i.e. physical ram minus a few reserved
bits and the kernel binary code)
MemFree: The sum of LowFree+HighFree
+MemAvailable: An estimate of how much memory is available for starting new
+ applications, without swapping. Calculated from MemFree,
+ SReclaimable, the size of the file LRU lists, and the low
+ watermarks in each zone.
+ The estimate takes into account that the system needs some
+ page cache to function well, and that not all reclaimable
+ slab will be reclaimable, due to items being in use. The
+ impact of those factors will vary from system to system.
