> When designing btrfs we took a big pile of known solutions for filesystem problems, crammed them together, and then fixed up the new problems that resulted. Somehow I missed the scientific magazine step that all the other filesystems have followed, but I'll do what I can to keep improving the FS.
Out of interest, what are your reasons for not having a peer reviewed article on this? Lack of familiarity of the process and/or time, would be my guess?
Especially since you benefited from reading a published paper, it would be nice for you to write up your changes. If you just don't want to go through that bother, maybe a "comment" would be nice? These are half-a-page comments to existing papers but they also get peer reviewed and published.
Actually, you mentioned that you worked with author of the original paper. Maybe he would be interested in publishing your work on your behalf.
