While I can appreciate the 2 patch approach for ease of review, patch 1
and patch 2 should be combined. Once you move a function into src/conf/*
- give it the vir* prefix.

Since you now have a function inside src/conf called from a driver, you
must add the function to src/libvirt_private.syms (otherwise your build
fails - at least mine did).

Additionally, once patches are combined virDomainCCWAddressSetCreate,
virDomainCCWAddressValidate, and virDomainCCWAddressAllocate (moved in
this patch) all become local/static to domain_addr and thus can be
removed from domain_addr.h and libvirt_private.syms

John

BTW: The ATTRIBUTE_NONNULL(3) ATTRIBUTE_NONNULL(4) from the .h file that
would then be "lost" could be added after the "static int" in the .c
file, although that's not a requirement. We're finding those are really
only useful if someone pass NULL as an argument and less useful if an
argument itself is NULL (which isn't the case here).

Woops! I missed that step.

I'm going to do this as part of a separate patch series which makes
several functions static which are unused elsewhere.

I will keep this in mind for my other patch series.

Thanks,
