I appreciate and thanks for your effort and time.

Yet I tend to avoid assuming if the inline is ok or not before
prepare_inode_buffer() since it will be free for space allocator
to decide inline or not at that time.

So personally I still would like to write a final compressed
index for inline fallback.

I will fix this issue myself later (it should be just a small
patch to fix this). 

Thanks for your effort on this issue again!

Thanks,
Gao Xiang
