Yes, good idea... fixing it like you said will guarantee correct free space
stats (apart for quotas) but not correct used-space and total-space stats
(they would be possible only for humfs if it uses some accounting).

However, by looking the code, I don't see an obvious way to trigger this
bug...
In:
static int hostfs_fill_sb_common(struct super_block *sb, void *d, int silent)
{
We have:
HOSTFS_I(root_inode)->host_filename = name;
And later, this value is reused (I actually checked this is supposed to refer
to the same thing) as:
err = do_statfs(HOSTFS_I(sb->s_root->d_inode)->host_filename,
So, could you double-check? I'll also try to reproduce it, if possible.
