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!
