  • Study of File System Evolution
    Study of File System Evolution Swaminathan Sundararaman, Sriram Subramanian Department of Computer Science University of Wisconsin {swami, srirams} @cs.wisc.edu Abstract File systems have traditionally been a major area of file systems are typically developed and maintained by research and development. This is evident from the several programmer across the globe. At any point in existence of over 50 file systems of varying popularity time, for a file system, there are three to six active in the current version of the Linux kernel. They developers, ten to fifteen patch contributors but a single represent a complex subsystem of the kernel, with each maintainer. These people communicate through file system employing different strategies for tackling individual file system mailing lists [14, 16, 18] various issues. Although there are many file systems in submitting proposals for new features, enhancements, Linux, there has been no prior work (to the best of our reporting bugs, submitting and reviewing patches for knowledge) on understanding how file systems evolve. known bugs. The problems with the open source We believe that such information would be useful to the development approach is that all communication is file system community allowing developers to learn buried in the mailing list archives and aren’t easily from previous experiences. accessible to others. As a result when new file systems are developed they do not leverage past experience and This paper looks at six file systems (Ext2, Ext3, Ext4, could end up re-inventing the wheel. To make things JFS, ReiserFS, and XFS) from a historical perspective worse, people could typically end up doing the same (between kernel versions 1.0 to 2.6) to get an insight on mistakes as done in other file systems.

  • Twenty Years of Berkeley Unix : from AT&T-Owned to Freely
    Twenty Years of Berkeley Unix : From AT&T-Owned to Freely Redistributable Marshall Kirk McKusick Early History Ken Thompson and Dennis Ritchie presented the first Unix paper at the Symposium on Operating Systems Principles at Purdue University in November 1973. Professor Bob Fabry, of the University of California at Berkeley, was in attendance and immediately became interested in obtaining a copy of the system to experiment with at Berkeley. At the time, Berkeley had only large mainframe computer systems doing batch processing, so the first order of business was to get a PDP-11/45 suitable for running with the then-current Version 4 of Unix. The Computer Science Department at Berkeley, together with the Mathematics Department and the Statistics Department, were able to jointly purchase a PDP-11/45. In January 1974, a Version 4 tape was delivered and Unix was installed by graduate student Keith Standiford. Although Ken Thompson at Purdue was not involved in the installation at Berkeley as he had been for most systems up to that time, his expertise was soon needed to determine the cause of several strange system crashes. Because Berkeley had only a 300-baud acoustic-coupled modem without auto answer capability, Thompson would call Standiford in the machine room and have him insert the phone into the modem; in this way Thompson was able to remotely debug crash dumps from New Jersey. Many of the crashes were caused by the disk controller's inability to reliably do overlapped seeks, contrary to the documentation. Berkeley's 11/45 was among the first systems that Thompson had encountered that had two disks on the same controller! Thompson's remote debugging was the first example of the cooperation that sprang up between Berkeley and Bell Labs.

Linus was born into the Swedish minority of Finland (about 5% of the five million Finns). He was a “math guy” throughout his schooling. Early on, he “inherited” a Commodore VIC- 20 (released in June 1980) from his grandfather; in 1987 he spent his savings on a Sinclair QL (released in January 1984, the “Quantum Leap,” with a Motorola 68008 running at 7.5 MHz and 128 kB of RAM, was intended for small businesses and the serious hobbyist). It ran Q-DOS, and it was what got Linus involved: One of the things I hated about the QL was that it had a read-only operating system. You couldn’t change things ... I bought a new assembler ... and an editor.... Both ... worked fine, but they were on the microdrives and couldn’t be put on the EEPROM. So I wrote my own editor and assembler and used them for all my programming. Both were written in assembly language, which is incredibly stupid by today’s standards.
