FreeBSD ZFSv13 進 RELENG_7

FreeBSD ZFSv13 終於進入 RELENG_7 了:「svn commit: r192498」。

幾個重要的改變:

  • kmem now goes up to 512GB so arc is now limited by physmem (kmem 再度拉高到 512GB)
  • the arc now experiences backpressure from the vm (which can be too much - but this allows ZFS to work without any tunables on amd64) (我不確定這個說明的意思,猜測是指當非 ZFS 需要系統資源時,cache 所使用的記憶體空間會放出來給 kernel 用)

另外 commit log 有個讓人還蠻在意的地方:
