[PATCH V2 0/3] block: avoid to drop & re-add partitions if partitions aren't changed

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 calling into ioctl(BLKRRPART).

V2:
	- don't save partitions state, and just check if current partition
	state is changed against partition devices	

Ming Lei (4):
  block: define parsed_partitions.flags as 'unsigned char'
  block: store partition flags into block_device
  block: re-organize blk_add_partitions
  block: avoid to drop & re-add partitions if partitions aren't changed
