Hi Herbert,

We are working at a new revision of [1] which enables BTRFS to use acomp for offloading zlib-deflate. We see that there is value in using QAT for such use case in terms of throughput / CPU utilization / compression ratio compared to software. Zlib-deflate is preferred to deflate since BTRFS already uses that format.
We expect to send this patch for 6.7. Can we keep zlib-deflate in the kernel?
Thanks,
