Btrfs: Fix integer overflow when calculating bytes_per_bitmap
On ppc64, bytes_per_bitmap will be (65536*8*65536). Hence append UL to fix integer overflow. Reviewed-by: Josef Bacik <jbacik@fb.com> Reviewed-by: Chandan Rajendra <chandan@linux.vnet.ibm.com> Signed-off-by: Feifei Xu <xufeifei@linux.vnet.ibm.com> Signed-off-by: David Sterba <dsterba@suse.com>
