[PATCH 0/2] Show cylinder sizes properly

[Linus Torvalds]

This is a seprate series of patches (it's on top of my first series in my 
tree, but I think it would apply independently) that came out of me 
looking at our cylinder size handling.

In particular, it came out of me noticing:
 "If you pick an existing type without work-pressure (eg a 10 l metric 
  bottle), it shows that "10 l" wet-size in cubic feet (0.35 cuft). It 
  should show it as 10 l because we don't have a workpressure, and we 
  just cannot convert to cuft at all"

and the first patch here fixes that issue.

The second patch is kind of a trial balloon, and shouldn't necessarily be 
taken seriously. What is does is to show *both* the nominal imperial size 
_and_ the "actual" size of an imperial cylinder. So if you have an AL80, 
it will now show up as havign the size "80 (77)cuft", where that 77 is our 
(approximate!) correction for the incompressibility of air.

I'm not sure it's actually a good idea, but with the first patch done for 
other reasons, it becomes trivial to show cylinder sizes in any random 
format, since it's not tied to that "get_volume_string()" that is used for 
other things too.

So I think the first patch is a good idea (although somebody should check 
whether we want to translate the liter and the cubic feet units). The 
second one is not really serious, and meant more as a "maybe we could talk 
about something like this" trial balloon.

Linus Torvalds (2):
  Don't use "get_volume_string()" for cylinder size string
  Show both the nominal and real size for an imperial cylinder
