IOCov: a framework to compute input and output coverage for file system testings

Introduction

This repository contains the source code for the paper "Input and Output Coverage Needed in File System Testing", which was used to measure input coverage of Metis and other file system testing tools including CrashMonkey, xfstests, and Syzkaller. We also include scripts to plot various figures in the HotStorage'23 and FAST'24 papers as well as kernel source code analysis for open flags and error codes.
