Hi Filipe,
So i knew what was wrong here, we need found_key while
btrfs_previous_extent_item() did set
it properly..^_^
I will send a v2 to fix this, thanks!

Since we have introduced btrfs_previous_extent_item() to search previous
extent item, just switch into it.

Hi Shilong,
This patch is making btrfs/004 fail for me, consistently:
I was trying to reproduce this xfstest failure(though we have known what's
wrong with my previous patch).
I did not really hit 004 failure, but i can reproduce btrfs/030 fail
consistently, i think you might be interested in this:

I test with latest btrfs-next and xfstest, with/without this patch applied, i
can not pass btrfs/030.
I don't know if there are some patches missing in btrfs-next.
Feel free to tell me if i miss something here.^_^
Ok I've reproduced this on my VM, I'll try and get this fixed up. Thanks,
Josef
