I checked Documentation/fs/vfs.txt, rkfs.. But i hadn't any reference to file str, superblock str, and so on that explains what its fields are for.. and cheking at the ext3 source code i see some functions ( ie: do_sync_write ) that i didn't know where to find info about ( without checking source code of this function ). is there some place that explains this? or the only way is to check code? thanks once again!
