Subject: Re: [PATCH v7 2/2] mm: support large folios swap-in for sync io devices

Hi Shakeel,

We submitted an RFC patchset [1] with the Intel In-Memory Analytics
Accelerator (Intel IAA) sometime back. This introduces a new 'canned-by_n'
compression algorithm in the IAA crypto driver.

Relative to software compressors, we could get a 10X improvement in zram
write latency and 7X improvement in zram read latency.

Thanks,
Kanchana
