Btrfs 的 Hash Collision…

Slashdot 上看到「Denial-of-Service Attack Found In Btrfs File-System」覺得很有趣,結果一看,又是 hash collision… XD

一年前的「n.runs-SA-2011.004 – web programming languages and platforms – DoS through hash table (PDF)」打爆所有主流語言,沒想到在 filesystem 上也發生了 XDDD

不知道要怎麼修正… (已經存在的資料要怎麼 migrate?incompatible change?)
