Good Job It is about time that we have this client for submission to the Kernel. I wish you guys a smooth and fun ride in. I intend to give this and hard drive and review, but before I do this. I'm missing from this patchset (this patch and the other 4) a Documentation/filesystems/orangefs.txt Documentation should include, among others, all needed Web URLS we need to fetch and Install a working system. A brief of the installation process. Farther reading, as well as as some 10 miles overview, philosophy of operation, basic structure ... Anything interesting to a Kernel developer ... I know that OrangeFS has excellent Documentation, it should be easy to collect some of the highlights into this Doc. Please see in above directory the Documentation of other FSs, for an example of scope and general interests. Your call what you want to put in there, my personal taste is: the more the better. One thing I would like to see in the [PATCH 0/4] (BTW please submit as a patchset with a Title [PATCH 0/X] email), A bit more detail about why OrangeFS is so nice, like Giga+ distributed Meta-Data, redundancy, scalability, layouts, GUI ... the works. A short sales pitch that will get us ordering two please.
