Omar Sandoval 3c72860b34 mm: export add_swap_extent() ... Btrfs currently does not support swap files because swap's use of bmap does not work with copy-on-write and multiple devices. See 35054394c4 ("Btrfs: stop providing a bmap operation to avoid swapfile corruptions"). However, the swap code has a mechanism for the filesystem to manually add swap extents using add_swap_extent() from the ->swap_activate() aop. iomap has done this since 67482129cdab ("iomap: add a swapfile activation function"). Btrfs will do the same in a later patch, so export add_swap_extent().
