From 82c003c914de17101ee8999ab3775e516cc76064 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Wed, 24 Feb 2016 11:08:50 -0800 Subject: gas pressures: do some initial cleanup This marks "surface_volume_multiplier()" static in preparation for changing it to use an actual honest-to-goodness compressibility estimation. Without that, it wasn't obvious that the function wasn't used in other random places. Also, remove the "wet_volume()" function. It was unused, but more importantly, it was wrong. Yes, it was the inverse of "gas_volume()", but when you calculate wet volumes from the imperial sizes, you don't actually use the "real" gas volume, you use the idealized one.
