This mechanism uses a RB tree to index a structure, which reserves some free blocks for an inode. * (Milestone 2) Run some benchmarks, such as dbench and blogbench. The result is in my project page (' http://wiki.freebsd.org/SOC2010ZhengLiu'). However, These benchmarks are deprecated because I get a new computer to run these benchmarks. Meanwhile, I will run each benchmark a few more times, such as 10. If run each benmark 10 times, the schedule will be delayed. Welcome to review it. lz
