From: Javier González <javier.gonz@xxxxxxxxxxx> This patchset extends zoned device functionality on top of the existing v3 ZNS patchset that Keith sent last week. Patches 1-5 are zoned block interface and IOCTL additions to expose ZNS values to user-space. One major change is the addition of a new zone management IOCTL that allows to extend zone management commands with flags. I recall a conversation in the mailing list from early this year where a similar approach was proposed by Matias, but never made it upstream. We extended the IOCTL here to align with the comments in that thread. Here, we are happy to get sign-offs by anyone that contributed to the thread - just comment here or on the patch. Patch 6 is nvme-only and adds an extra check to the ZNS report code to ensure consistency on the zone count. The patches apply on top of Jens' block-5.8 + Keith's V3 ZNS patches. Thanks, Javier Javier González (6): block: introduce IOCTL for zone mgmt block: add support for selecting all zones block: add support for zone offline transition block: introduce IOCTL to report dev properties block: add zone attr. to zone mgmt IOCTL struct nvme: Add consistency check for zone count block/blk-core.c | 2 + block/blk-zoned.c | 108 +++++++++++++++++++++++++++++++++- block/ioctl.c | 4 ++ drivers/nvme/host/core.c | 5 ++ drivers/nvme/host/nvme.h | 11 ++++ drivers/nvme/host/zns.c | 69 ++++++++++++++++++++++ include/linux/blk_types.h | 6 +- include/linux/blkdev.h | 19 +++++- include/uapi/linux/blkzoned.h | 69 +++++++++++++++++++++- 9 files changed, 289 insertions(+), 4 deletions(-) -- 2.17.1
