Oh, I just forgot to mention that the kernel is 2.4.19 and gcc version is
3.2. I also used uml to trace it, and I found that the 'magic' happens
within get_new_inode():
....
inode->i_sb = sb;
...
if (sb->s_op->read_inode2) sb->s_op->read_inode2(inode, opaque);
else sb->s_op->read_inode(inode);
just before sb->s_op_read_inode() is executed, inode->i_sb is still sb.
But once the function (which is snet_read_inode()) is called, inode->i_sb
just magically point to some other place.
