[PATCH 0/4] btrfs: out-of-band (aka offline) dedupe v4
...de Perthuis also has a bedup branch which works against this ioctl.
The branch can be found at:
https://github.com/g2p/bedup/tree/wip/dedup-syscall
Limitations
We can''t yet dedupe within the same file (that is, source and destination
are the same inode). This is due to a limitation in btrfs_clone().
Code review is very much appreciated. Thanks,
--Mark
