Currently libspl is a static archive that is linked into multiple shared objects, which then re-export its symbols. We intend to fix this soon. For the moment though, most programs shipped with OpenZFS depend on two or more of these shared objects, and see the same symbols twice. For functions this is not a problem, as they do not have any mutable state and so the linker can simply select the first one and use that for all. For global data objects however, each shared object will have direct (non-relocatable) references to its own instance of the symbol, such that changes on one will not necessarily be seen by the other. While this shouldn't be a problem in practice as these reexported interfaces are not supposed to be used, they are technically undefined behaviour in C (C17 6.9.2) and are reported by ASAN as a violation of C++'s "One Definition Rule". To fix this, we hide these globals inside their compilation units, and add access functions and macros as appropriate to preserve the existing API (though not ABI).
