Re: [PATCH v4 0/6] Btrfs in-band de-duplication test cases

[Qu Wenruo <quwenruo@cn.fujitsu.com>]

Please don't merge this patchset.

As the there is some naming undecided recently.

The abbreviation 'dedup' may be changed to 'dedupe'.
I'll update them when all related parts is settled down.

Thanks,
Qu
