The Linux kernel is permeated with constant values that are critical to system performance. Many of these constants, referred to as _perf-consts_, are magic numbers with brittle assumptions on hardware and workloads. Unfortunately, there is no capability of _in-situ_ tuning of perf-const values o...

Fast storage hardware and computational SSDs have outpaced the traditional kernel-centric or kernel-bypass file system designs, fragmenting modern storage stacks across library file systems, kernel subsystems, and in-device file systems. Each architecture offers only a subset of desired propertie...
