7b63bf1d27 !!!!! -> increasing the offset has to be done inside the fs/chardriver. 
- rewrite the initrd_read/write, char_driver r/w. Now all functions use fildes_t instead of vfs_node_t structs.
- eleminate some compiler warnings
- some changes in open, to reduce compiler warnings. This function isn't working yet!

3d74f1b514 - rewrite the read_fs and write_fs. Now both functions use fildes_t instead of vfs_node_t structs. 
INFO:	typedef struct fildes {
        	vfs_node_t* 	node;
        	off_t 		offset;
		int 		flags;
		int 		mode;
	} fildes_t;

- merge fs_types.h and fs.h into one file fs.h
