I don't know the memory management well enough to state which way is
correct. Re-reading the previous threads it didn't seem you were sure
either.
The whole thing comes down what is used memory?
Take total memory and subtract the free memory, that's an easy start.
We also remove buffers and cache and slab (though its not in the man
page).
The last is the problem, slab has reclaimable and non-reclaimable parts.
We remove both for the used memory, but I can see non-reclaimable is
*really* being used so should stay (and we only remove reclaimable).
However there is now available. So should there be a difference between
the two? Why are some things excluded from free and not available?
I have 1.8G used, 1.2G free and 13.8G available.
So 1.2G isn't used at all, but about 12.6G is used but could be
returned?
