Filesystem error handling

We’re going to reproduce some results from papers on filesystem robustness that were written up roughly a decade ago: Prabhakaran et al. SOSP 05 paper, which injected errors below the filesystem and Gunawi et al. FAST 08, which looked at how often filessytems failed to check return codes of functions that can return errors. Prabhakaran et al. injected errors at the block device level (just underneath the filesystem) and found that ext3, resierfs, ntfs, and jfs mostly handled read errors reasonb...
