Oh, and please, I beg you, consider increasing the hardlink limit to >16
bit - look at other filesystems,. many filesystems thought they could get
away with 16 bit (ext*, xfs, ...) but all of them nowadays support 31 bit
or more for the hardlink count :) Merely 18 bits would probably suffice :)
While 65535 will just work at the moment for me (my largest directory has
~62000 subdirectories, and I can half this wiht some extra work), it's
guaranteed to fail sooner or later.
Thanks for listening (even if you decide against it :).
