Hello, Sorry ... this mail is not directly Linux-related but ... I'm learning the file system domain under UNIX (and Linux) and there are a few "well-know" papers that I cannot find. Here are the references: Bina E. & Emrath P. A faster fsck for BSD Unix. Usenix 1989. Kleiman S. Vnodes: An architecture for Multiple File System Types. Usenix 1986. McKusick M., Joy W., Leffler S. & Fabry R. A Fast File System for Unix. ACM 1984. If you know where I could find those papers, it would be very nice. Thanks in advance, Olivier
