This is the final patch in the patch series implementing snapshots. This patch implements two new ioctls that work like creation and deletion of directories, but fancier. - BCH_IOCTL_SUBVOLUME_CREATE, for creating new subvolumes and snaphots - BCH_IOCTL_SUBVOLUME_DESTROY, for deleting subvolumes and snapshots Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
