This "feature" is severely broken and yes, outright removal is what I'd
suggest for a fix.  HFS+ allows hardlinks to files, which means that
you allow multiple dentries for the same inode with ->lookup() in it,
which is asking for deadlocks.

This is fundamentally not supported.  Considering that forks are lousy
idea in the first place, I'd seriously suggest to remove that idiocy for
good.
