Subject: [PATCH 0/2] block: avoid to drop & re-add partitions if partitions aren't changed
Date: Fri, 5 Feb 2021 10:17:06 +0800 [thread overview]
Message-ID: <20210205021708.1498711-1-ming.lei@redhat.com> (raw)
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
