90% when converting _to_ XFS. It's an estimation, not an absolute 
number... on a very large disk it may be slightly higher.

you can count the number of hard links with this command:

find /path/to/filesystem -xdev -type f \! -links 1 | wc -l

it's not exact, as each file with N links will be counted N times, but 
you will get a rough idea.
