While for the original library's purposes these functions of course want
to be externally exposed, we don't need this, and we also don't want
this both to prevent unintended use and to keep the name space tidy.
(When functions have no callers at all, wrap them with a suitable
#ifdef.) This has the added benefit of reducing the resulting binary
size - while this is all .init code, it's still desirable to not carry
dead code.
Additionally in the hypervisor we don't need the bulk of unzstd(), so
insert a conditional allowing the compiler to DCE the rest (including
the called functions).

So I understand the desire to keep the code close to Linux and removing
the dead code. However I am still not convinced that the approach taken
is actually worth the amount of memory saved.
How much memory are we talking about here?

There are no (runtime) memory savings, as is being said by the
description. There are savings on the image and symbol table sizes
(see below - .*.0/ holding files as produced without the patch
applied, while .*.1/ holding output with it in place), the image
size reduction part of which is - as also expressed by the
description - a nice side effect, but not the main motivation for
the change.

Thanks for the providing the information. I have misunderstood your
original intention.
Reading them again, I have to admit this doesn't really change my view
here. You are trading a smaller name space or prevent unintended use
(not clear what would be wrong to call them) to code
maintenability/readability.
At the same time, this is not a code I usually work on (even if I am
meant to maintain it). I will leave another maintainer to make the
decision here.
Cheers,

Well, I mean mainly the usual issue of us, short of having Linux-like
section reference checking, being at risk of calling __init functions
from non-__init code. This risk exists with every single such symbol,
and hence I view it as helpful to reduce overall risk by limiting the
number of such symbols to the actually useful ones.

Fair enough. Thanks anyway for looking here, and for all the other
acks on this (originally larger) series.

Right, we are rely on the review to not mix the tow. In the past, I have
successfully used the Linux script on Xen binary. It might be a good
idea to import a cut-down version in Xen.

May I ask for another REST maintainer's view here? If there's support
for Julien's position, then I'll at least know to drop the patch. Of
course I'd prefer it, or a stripped down version of it, to go in.
Thanks, Jan

FTR - a response to this was iirc supplied on a community call (by
Andrew), requesting to actually delete the sections of code enclosed
in BUILD_DEAD_CODE conditionals. I've been pondering the request for
quite some time, and I've now come to the conclusion that I do not
want to do so. Hence, while I'm not happy about this, I'll treat this
patch as rejected.
