This patchset adds support for Linux copy_file_range() syscall usage via a new '--reflink' copy-out parameter. The syscall can considerably improve archive creation performance and space efficiency on copy-on-write filesystems such as XFS and Btrfs by performing a metadata only reflink instead of regular read/write copy.
