I want to create a case insensitive "wrapper" filesystem (say 'casefs') but I do not know enough about the internals to know where to intercept things. I would really appreciate some pointers on how to get started. I have read the variety of VFS documents but this seems like it demands a deeper understanding (if it's possible at all). The most optimistic solution I can think of would be to just create a filesystem module that simply returned the super_block of an already mounted filesystem. Otherwise even if I create a casefs specific super_block I don't think I want to start creating inodes as I really want this to be a "wrapper" into another fs so I do not see why I would want to go lower than that correct? So in casefs_read_super I would use get_fs_type of whatever type (passed as a module parameter perhaps) to get a file_system_type and enumerate fs_supers to find the super_block of interest and just return that? Is it safe to return the super_block of a mounted filesystem and what happens to the one allocated for casefs_read_super? Or will I need to create a casefs specific superblock and selectively copy over the bits of interest? Thanks, Mike -- A program should be written to model the concepts of the task it performs rather than the physical world or a process because this maximizes the potential for it to be applied to tasks that are conceptually similar and, more important, to tasks that have not yet been conceived. -- Kernelnewbies: Help each other learn about the Linux kernel.
