However, it\u0027s still vulnerable to infinite\nloops that come in via the next_unlinked pointers.\n\nFix this problem by remembering which inodes we\u0027ve 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\u0027ll deal\nwith the second case in a subsequent patch."
