I am working on ramfs filesystem code. I would like to modify the directory
path while creating the file.
example when we give mkdir newfile; // this newfile should be present in
/newlabel/newfile
                                                           // newlabel is
prefixed before the newfile


So i am trying to modify the functions defined in the struct
inode_operations for the directory.

static const struct inode_operations ramfs_dir_inode_operations = {
    .create     = ramfs_create,
    .lookup     = simple_lookup,
    .link       = simple_link,
    .unlink     = simple_unlink,
    .symlink    = ramfs_symlink,
    .mkdir      = ramfs_mkdir,
    .rmdir      = simple_rmdir,
    .mknod      = ramfs_mknod,   //Modifying this function to add the prefix
to the file
    .rename     = simple_rename,
};

Let me know if I am doing something wrong

Thanks
Dinesh
