For now, write compressed file with fsync, we need do CP, it's a heavy
behavior. This patch try to support forward recovery for compressed file.
This is a rough version, need more test to improve it.
Anyway, looking forward some suggestions.
When test this patch, you should disable CP when fsync
Please ignore this...
I'll send a new version.
Thanks.

This patch may will make random write bench score reduce a lot.
In my test, use fio test randwrite, config as below:
[global]
direct=1
numjobs=1
time_based
runtime=60
ioengine=sync
iodepth=16
filename=fio-test
buffer_pattern=0x00
[file5]
name=fio-rand-write
rw=randwrite
bs=4K
size=128M
