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 :).
