However, it's still vulnerable to infinite\nloops that come in via the next_unlinked pointers.\n\nFix this problem by remembering which inodes we've already seen and\nchecking new agino pointers against that.  If a bit is already set,\neither this is a loop or the inode has nonzero link count.  We'll deal\nwith the second case in a subsequent patch."
