Kent Overstreet	65bc410907	mean and variance: More tests ... Add some more tests that test conventional and weighted mean simultaneously, and with a table of values that represents events that we'll be using this to look for so we can verify-by-eyeball that the output looks sane.

Daniel Hill	92095781e0	bcachefs: Mean and variance ... This module provides a fast 64bit implementation of basic statistics functions, including mean, variance and standard deviation in both weighted and unweighted variants, the unweighted variant has a 32bit limitation per sample to prevent overflow when squaring.
