After it the /foo/bar file will have its name removed from the filesystem tree (and from the on-disk data too), but since the file is still held by the process (this structure is explained in the article about [[dumping files]]), the blob with data itself is still there.

There are two different sub-cases in this scenario. First, when the number of hard links associated with the file is zero, i.e. the /foo/bar name was the last one removed or the only it ever had. Another situation is when the link count is not zero. This means that some other name (hard link) for this file exists. In the latter case it's important to notice, that Linux VFS layer generally does ''not'' allow to find out this other name. Sometimes it's possible, but typically it's not.
