Must it be exactly right, or is it ok with a value that is slightly
larger? More precisely, it seems like the easiest way to get a
reasonable st_nlink field in shadowfs is to add up the st_nlink fields
of the corresponding underlying directories, adjusting for the ±2 terms.

Then you will get the correct value + the number of files that are
actually shadowing each other.

If a process that traverses the tree finds that readdir returns fewer
entries than st_nlink of a previous stat indicates, it can't know if
that's because stat lied or because some files were unlinked under its
feet.
