2020-02-22Make hard link detection scale betterDavid Oberhollenzer
Instead of doing a linear search, which scales quadratically, use a red-black tree with inode numbers as key for finding hard links. To reiterate: we can't just use a flat table, because the SquashFS file is potentially untrusted and the inode numbers can be anything, no matter what the super block says.
