Subject: [PATCH 0/2] block: fix discard merge for single max discard segment
Date: Tue, 11 Aug 2020 17:21:32 +0800 [thread overview]
Message-ID: <20200811092134.2256095-1-ming.lei@redhat.com> (raw)
Hello,
The 1st patch checks max discard segment limit in request merge code,
and one discard request failure issue is fixed for virtio_blk.
The 2nd patch fixes handling of single max discard segment for
virtio_blk, and potential memory corruption is fixed.
Ming Lei (2):
block: respect queue limit of max discard segment
block: virtio_blk: fix handling single range discard request
block/blk-merge.c | 10 ++++++++--
