Subject: drop bio mode from null_blk and convert it to atomic queue limits v4
Date: Tue, 20 Feb 2024 10:32:43 +0100 [thread overview]
Message-ID: <20240220093248.3290292-1-hch@lst.de> (raw)
Hi Jens,
sorry for spamming you twice in a day with this series, but the buildbot
decided to send me a delayed warning just after posting the previous
series, so I've fixed it up and resent.
this series drops the obsolete bio mode from the null_blk driver and
then converts the driver to pass the queue limits to blk_mq_alloc_disk.
Changes since v3:
- fix the !BLK_DEV_ZONE compilation
Changes since v2:
- rebase on top of the blk_alloc_disk prototype change
Changes since v1:
- add an incremental from Damien to make sure the zoned tunable are
properly taken into account
