[ext2fs] status report 1

Status:

 * (Milestone 1) Implement a preallocation algorithm --  reservation 
window  mechanism.
    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.
