Hello Matthew, thank you for reviewing my patch! Whoops, no module uses this symbol in this patch. I was working on a similar patch series (accounting zswap statistics on a per-lruvec level [1]) where I did the same thing, and needed to export this so that using it in zsmalloc wouldn't break if zram was built as a module. Obviously there's no need for exporting for this patch but I forgot to drop that part when copying this over from that series. Sorry for the noise! Thanks again for catching this. I hope you have a great day! Joshua [1] https://lore.kernel.org/all/20260311195153.4013476-10-joshua.hahnjy@gmail.com/
