Preparation patchset for incoming (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_20160205 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. v5: Minor documentation modification for 'btrfs dedup enable' Qu Wenruo (7): btrfs-progs: Basic framework for dedup command group btrfs-progs: dedup: Add enable command for dedup command group btrfs-progs: dedup: Add disable support for inband deduplication btrfs-progs: dedup: Add status subcommand btrfs-progs: Add dedup feature for mkfs and convert btrfs-progs: Add show-super support for new DEDUP flag btrfs-progs: debug-tree: Add dedup tree support Wang Xiaoguang (1): btrfs-progs: property: add a dedup property Documentation/Makefile.in | 1 + Documentation/btrfs-dedup.asciidoc | 126 ++++++++++++++ Documentation/btrfs-property.asciidoc | 2 + Documentation/btrfs.asciidoc | 4 + Documentation/mkfs.btrfs.asciidoc | 9 + Makefile.in | 2 +- btrfs-convert.c | 19 ++- btrfs-debug-tree.c | 4 + btrfs-show-super.c | 17 ++ btrfs.c | 1 + cmds-dedup.c | 304 ++++++++++++++++++++++++++++++++++ commands.h | 2 + ctree.h | 42 ++++- dedup.h | 42 +++++ ioctl.h | 23 +++ mkfs.c | 8 +- print-tree.c | 94 +++++++++++ props.c | 73 ++++++++ utils.c | 47 ++++-- utils.h | 7 +- 20 files changed, 802 insertions(+), 25 deletions(-) create mode 100644 Documentation/btrfs-dedup.asciidoc create mode 100644 cmds-dedup.c create mode 100644 dedup.h -- 2.7.0 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
