It's a per-file limit

I'm mostly using ext3.  Limit of 32,000.

According to fs/ext4/ext4.h ext4 has a limit of 65,000,
although googling about implies that there's a 16
bit counter somewhere so it could be 65,536.
And if you're getting 70-80 million then
that's obviously wrong.


  for ((i=1;i=$i+1;i<0)); do ln foo foo$i || break; done

I get 65,000.  But I know that's the directory
size limit so this is not necessarily a good test
since all the links are in a single directory.

I tend to hit the hardlink limit on my ext3 fs-s
around 300 --link-dest-ed backups.
