当听着FAST‘13’‘ffsck：the Fast File System Checker’‘[1]的第一篇论文的陈述时，我立刻想知道我是否可以在FreeBSD中实现一些想法。研究人员的目标是重新组织Linux ext3文件系统，并重写其文件系统检查器，以便可以更快地完成对文件系统的完整检查。通过添加几百行代码，我能够实现对fsck的改进和FreeBSD文件系统(FFS)中的布局策略。
W hile listening to the presentation of the first paper at FAST ’13, ‘‘ffsck: The Fast File System Checker’’ [1], I immediately wondered whether I could implement some of the ideas in FreeBSD. The researchers’ goal was to reorganize the Linux ext3 filesystem and to rewrite its filesystem checker so that a complete check of the filesystem could be done more quickly. With the addition of a couple of hundred lines of code, I was able to implement both the improvements to fsck and the layout policy in the FreeBSD filesystem (FFS).
