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
