Nothing. It is just no more referenced in the corresponding
filesystem_hard_link_read object.
- ---
~ void forget_etiquette(file_etiquette *obj);
~            // tell the filesystem module that the reference of
~            // that etiquette does not
~            // exist anymore (not covered by filter for example)
- ---

And what about the hard links, if they are not
| filtered?

when a plain file is linked sevral time to the directory tree, the
filesystem_hard_link_read class produces for the first occurence of a
reference to this file an object of the class file_etiquette then for
each following reference an object of the class hard_link.

This is never a hard_link object that is used to call forget_etiquette()
[argument type does not match], this method is only applied to
file_etiquette files.

If so applied, because the first occurence is filtered out, the
filesystem_hard_link_read has forgotten about this inode and for the
next occurence met, it will produce a new file_etiquette object not a
hard_link object.

The idea behind this is to not have hard_links objects in an archive
that have a file_etiquette as reference that has been excluded from the
archive, making theses hard_links object impossible to use for
restoration as example (if used this would lead to SEGFAULT or the like).

| For example, I'm thinking
|
| inode	file
|
| 20	a/a
| 20	b/a
| 20	c/a
| 20	d/a
|
| if b is excluded, how does this work?
|
| a/a -- <20,a/a>
| b   -- delete what?
| c/a -- ?
| d/a -- ?
