All snapshot related code, except bdrv_snapshot_dump() and bdrv_is_snapshot(), is moved to block/snapshot.c. bdrv_snapshot_dump() will be moved to another file later. bdrv_is_snapshot() is not related with internal snapshot. It also fixes small code style errors reported by check script. Signed-off-by: Wenchao Xia <xiawenc@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
