I hope I am understanding the question correctly :) If you look at the function unpack_to_rootfs(), it makes repeated calls to write_buffer(). This is the "destination" of the unpack. write_buffer() is a state machine that calls different functions depend on the current state. These functions call vfs functions like sys_open() with O_CREAT (in do_name()) and sys_write() with the unpacked data (in do_copy()). I do not know the state of the vfs at this moment, however. > rday Vegard -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
