## AI overview

Linux developer Usama Arif's two-patch series for Zswap separates compression and decompression requests, waits, and mutexes to reduce load contention. For synchronous software compressors, decompression can use an on-stack request without taking the Zswap lock. The reported tests show lower worst-case read times and fewer slow reads across 1- and 8-vCPU runs; the patch series is under review on the Linux kernel mailing list.
