Hi Guys,

The two patches changes block ioctl(BLKRRPART) for avoiding drop &
re-add partitions if partitions state isn't changed. The current
behavior confuses userspace because partitions can disappear anytime
when ioctl(BLKRRPART).

  block: move partitions check code into single helper
  block: avoid to drop & re-add partitions if partitions aren't changed
