Subject: [PATCH v4 0/8] btrfs-progs: Support in-band de-duplication
Date: Tue, 2 Feb 2016 10:59:05 +0800 [thread overview]
Message-ID: <1454381953-29676-1-git-send-email-quwenruo@cn.fujitsu.com> (raw)
Preparation patchset for in-coming (aimed for 4.6) kernel in-band
de-duplication patchset.
New kernel dedup will has 2 different dedup backends and a ioctl
interface to enable/disable dedup.
The ioctl interface and on-disk format (mostly) is determined, so submit
this patchset first before de-duplication first.
The patchset can also be fetched from github:
https://github.com/adam900710/btrfs-progs.git dedup
v2:
Better objectid/offset format for dedup hash items
Output hash for dedup hash items
v3:
Keep dedup tree objectid and ro_flag the same with kernal,
since the tree objectid 11 and ro_flag 1 are all taken by space cache
tree v2.
Add dedup property support.
v4:
Better debug tree output for dedup tree
Update document to keep consist with new default values.
