I understand you’ll need this mTHP swap-in series to leverage your IAA for parallel decompression, right? Without mTHP swap-in, you won't get this 7X improvement, right? This is another important use case for the mTHP swap-in series, highlighting the strong need to start the work from the sync IO device. I’ll try to find some time to review your patch and explore how we can better support both software and hardware improvements in zsmalloc/zram with a more compatible approach. Also, I have a talk[1] at LPC2024—would you mind if I include a description of your use case? [1] https://lpc.events/event/18/contributions/1780/ > > Thanks, > Kanchana Thanks Barry
