As someone already said here - the link count is 0. The problem is that
when you delete a file and somebody has it open its link count is set
to 0 (and the directory entry is deleted) but the file is deleted after
it is closed. At that time is also set dtime. So it can happen that
link count is set to 0 but dtime not (it happened in some kernels that
fs could be unmounted even if there were some files open..) and fsck
complains about this inconsistency...
