Subject: [PATCH V2 0/4] blk-mq: queue mapping fix & improvement
Date: Mon, 17 Dec 2018 18:42:44 +0800 [thread overview]
Message-ID: <20181217104248.5828-1-ming.lei@redhat.com> (raw)
Hi,
The 1st patch fixes allocation for queue mapping table.
The 2nd patch fixes shared queue mapping, which may cause IO
hang in case that both write_queues and poll_queues are zero.
The 3rd patch fixes dispatch from sw queue when there is either
write queue or poll queue.
The 4th patch exports hctx->type in debugfs, so that we can write
debugfs based test for verifying if queue mapping is valid.
V2:
- remove hctx->type export from sysfs
- take hch's patch to fix shared queue mapping
- add the patch 3
