Hi, The following series of patches implements in btrfs an ioctl to do out-of-band deduplication of file extents. To be clear, this means that the file system is mounted and running, but the dedupe is not done during file writes, but after the fact when some userspace software initiates a dedupe. The primary patch is loosely based off of one sent by Josef Bacik back in January, 2011.

Hi everyone, I described the reflink operation at the Linux Storage & Filesystems Workshop last month. Originally implemented as an ocfs2-specific ioctl, the consensus was that it should be a syscall from the get-go. Here's some first-cut patches. For people who have not seen reflink, either at LSF or on the ocfs2 wiki, the first patch contains Documentation/filesystems/reflink.txt to
