Hi there, (few paragraphs of introductory blabla, precise question at the bottom!) I'm a c/c++ programmer but never done anything with the kernel (except config and compile!)... but I have been thinking about a few things and I'm sure they may not help the world very much but might still be interesting projects to learn a great deal. I was thinking on making a new VFS (as i understand it the VFS is what receives all FS related calls, and translates those calls depending on the end-device's drivers, as i understand, it works this way: fs call from userspace -> VFS -> Raid(for example) -> ext2 ). The new VFS would do the same work as the current VFS, but would add more logging and statistics capabilities. I was thinking on filtering like what file is read and when, what file is written and when. Thats the basic, and this info would be logged into a SQL database (probably sqlite) for a better analysis later. The final goal of this thing would be to help in making automated incremental backup that could do something as flexible as trigger a script with the list of files that needs to be backed up, so this script can do anything the user has specified (copy&compress, copy to a remote destination, etc...). I dont think this is a super advantage to anyone and i understand most of the work would for near nothing... but my real real goal is to learn & practice kernel coding (get my hands dirty for once!) and to learn how files are handled on linux (at a more low level). My question is: if i read on VFS, is this the correct keyword for what I intend to do? Is there anything else that is closely related that I would need to read? (i mean specific to my project, i already have links to more general kernel dev). And is there any such kind of project that I could look into, reuse and extend possibly?
