Hi Jens,
1st patch modifies blk_mq_plug() function to disable plugging for
write and write zeroes in zoned block devices.
2nd patch uses the blk_mq_plug function in the block layer consistently.
The patches are based on next-20220923.
Changes since v2:
- Enhance the commit log for the 2nd patch (Christoph)
Changes since v1:
- Explicltly check only for write and write zeroes as they require zone
locking in blk_mq_plug
- create a new helper to check for ops that require zone locking for
zoned devices and also reuse it in blk_req_needs_zone_write_lock
Pankaj Raghav (2):
block: adapt blk_mq_plug() to not plug for writes that require a zone
lock
block: use blk_mq_plug() wrapper consistently in the block layer
