Subject: Re: [PATCH v5 6/6] zsmalloc: Implement writeback mechanism for zsmalloc 

Thanks a lot for the suggestions so far and for the review, Minchan!
Quick question about your last comment:

>> +#endif

free_handles() here is for the deferred handle freeing, which is also
under CONFIG_ZPOOL now, so I don't think we should remove the #ifdef
CONFIG_ZPOOL here, no? Let me know if I'm misunderstanding your
suggestion, or if you have any further comments regarding this patch.
