I helped bring up the first instance of ZFS running as a kernel module on Halloween, 2002 (one fun week staying up all night hacking with Jeff Bonwick). The earliest code was written in either 2001 or just possibly 2000 - so 5-6 years in elapsed time. On the other hand, in terms of total programmer staff-years put into ZFS, it's on the order of 25 years. I'm not sure either what the best route to the next big Linux file system is - start from scratch or reuse a lot of code. One of the things I want to talk about at the workshop is creative reuse of existing code, a la the continuation inode idea. -VAL - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
