This one looks interesting - I wonder what kind of client use it gets.
FICLONERANGE / BTRFS_IOC_CLONE_RANGE is atomic, so it should be possible
to extend Samba's current dup-extents support to handle the new flag
(DUPLICATE_EXTENTS_DATA_EX_SOURCE_ATOMIC) without needing any lower
level changes.

Cheers, David
