Well, except for the fact that the one for FFS_MEDIAERR required splitting the
uses into -ENODEV, -EIO, and -ENOENT.

Also, "and remover the stupid blocks" would be a second change, and I *thought*
the rule was "one thing, one patch".

Reviewing a patch where you know that exactly one thing is supposed to happen
means scrolling through 14 occurrences of the pattern

 	if (num_alloced == 0)
-		ret = FFS_FULL;
+		ret = -ENOSPC;

goes *really* fast, and those comprise most of the bulk of the patchset.

And as I already mentioned, the "stupid looking blocks" will be removed in
a future patch.
