Typically when filesystem uses get_empty_inode, it installs the value
from the superblock s_flags fields into i_flags, so that the inodes
inherit the properties from the superblock.

For networks there's no formal superblock, but conceivably you could
define network namespaces that could use them. Or the i_flags might be
useful to networking in some way.

But it's hardly worth arguing about; if you feel that strongly about it,
send Linus a patch for get_empty_inode(). One extra cleared field isn't
going to hurt performance.
