i dont think generic names like that would be allowed in global space
for this exact reason. ive already made sure all the data/function
symbols that are visible from a linkage stand point are properly
namespaced because unlike structures, those are externally visible by
tools such as kallsyms.
i'd really prefer to not have to redo all these patches considering
this one change will cascade into like 20 others. i'd be a lot more
amendable to a patch on top of all of these that namespaces the
structs.
