This patch implements functionality for following ioctls:
BTRFS_IOC_SNAP_CREATE - Creating a subvolume snapshot
Create a snapshot of a btrfs subvolume. The snapshot is created using the
ioctl's third argument that is a pointer to a 'struct btrfs_ioctl_vol_args'
(which was mentioned in the previous patch). Before calling this ioctl,
the fields of the structure should be filled with aproppriate values for
the file descriptor and path of the subvolume for which the snapshot is to
be created.
BTRFS_IOC_SNAP_DESTROY - Removing a subvolume snapshot
Delete a snapshot of a btrfs subvolume. The snapshot is deleted using the
ioctl's third argument that is a pointer to a 'struct btrfs_ioctl_vol_args'
(which was mentioned in the previous patch). Before calling this ioctl,
the fields of the structure should be filled with aproppriate values for
the file descriptor and path of the subvolume for which the snapshot is to
be deleted.
Implementation notes:
Since the thunk type 'struct btrfs_ioctl_vol_args' is defined in the
previous patch, the implementation for these ioctls was straightforward.
