Linux "SpadFS is a new filesystem that I design and develop as my PhD thesis. It is an attempt to bring features of advanced filesystems (crash recovery, fast directories) and good performance without increasing code complexity too much. Uses crash counts instead of journaling (because journaling is too complex and bug-prone) and uses hash instead of btrees for directory organization."
