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).

Which is the f***king point of BLKRRPART and the behavior it had
since day 1.  Please fix the application(s) that all it all the time
instead of bloating the kernel, as said before.
