Which part are you interested in? Getting mount attributes? Or a generic key-value retrieval and storage interface? For the first one there are multiple proposals, one of them is adding a new system call using binary structs. The fsinfo(2) syscall was deemed overdesigned and rejected. Something simpler would probably be fairly uncontroversial. As for the other proposal it seems like some people would prefer a set of new syscalls, while some others would like to reuse the xattr syscalls. No agreement seems to have been reached. Also I think a notification system for mount related events is also a much needed component. I've tried to explore using the fsnotify framework for this, but the code is pretty convoluted and I couldn't get prototype working. Thanks, Miklos
