Hi again,

I made a mistake on the second line of suggestions in my previous mail.

One should read:

• "Physical Used" should be mapped to "buff/cache" + "used"

Sorry for the inconvenience, Dominique

Well, previously there had just been the physical measurement, but the addition of the buffer/cache distinction allowed 'Actual Used' to be a more meaningful reference point.

I think it definitely makes sense to have 'Actual Used' align with the (inverse of the) Available memory metric when the kernel provides one.

Operating by the principle of least surprise, it's probably best to continue with the original formula for Physical Used, however. (Ironically.)

This patch should revert the Physical Used value to its previous composition.
