Hi, Gao,
But if there is some deduplciated chunks in the logical dsunit
boundary, don't align it at all since there is no real benefit.
Although I'm still not sure what's the default behavior of `dsunit`
for chunks.
Exactly, if `--chunksize=40

Hi, Gao,
What's your `--chunksize` ? consider the following:
chunksize = 4096
dsunit = 512 = 2M
and two inodes:
inode A (8k)2M, 2M+4k
inode B (12k) 4M, 2M, 4M+4k, 4M+8k?
Is it possible? what's the expected behavior of

Hi, Gao,
Thanks for your review !
As for this patch, what if the inode itself is
chunk-deduplicated, could we apply this if the inode
only has one new chunk instead at least for now?
Do you mean inode has 3 chunks, chunk#2 and chunk#3 dupli
