This is a userland part of zoned block device support for btrfs. Kernel side patch series: https://lore.kernel.org/linux-btrfs/20190808093038.4163421-1-naohiro.aota@xxxxxxx/T/ Please see the kernel side for general description of zoned block device support. Patches 1 and 2 introduce some modification to prepare for the later patches. Patch 3 enable zoned support for the configuration script. Patches 4 to 6 introduce functions to retrieve zone information from a device and call them when opening a device. Patches 7 to 12 adopts current implementations e.g., extent allocation for HMZONED mode. Patches 13 to 15 enables HMZONED mode in various sub-commands. v2 https://lore.kernel.org/linux-btrfs/20190607131751.5359-1-naohiro.aota@xxxxxxx/ v1 https://lore.kernel.org/linux-btrfs/20180809181105.12856-1-naota@xxxxxxxxx/ Changelog: v3: - Unified userland code and kernel code - Introduce common/hmzoned.c and put hmzoned related code there Naohiro Aota (15): btrfs-progs: utils: Introduce queue_param helper function btrfs-progs: introduce raid parameters variables btrfs-progs: build: Check zoned block device support btrfs-progs: add new HMZONED feature flag btrfs-progs: Introduce zone block device helper functions btrfs-progs: load and check zone information btrfs-progs: avoid writing super block to sequential zones btrfs-progs: support discarding zoned device btrfs-progs: support zero out on zoned block device btrfs-progs: align device extent allocation to zone boundary btrfs-progs: do sequential allocation in HMZONED mode btrfs-progs: redirty clean extent buffers in seq btrfs-progs: mkfs: Zoned block device support btrfs-progs: device-add: support HMZONED device btrfs-progs: introduce support for device replace HMZONED device Makefile | 2 +- cmds/device.c | 29 +- cmds/inspect-dump-super.c | 3 +- cmds/replace.c | 12 +- common/device-scan.c | 10 + common/device-utils.c | 85 +++++- common/device-utils.h | 4 + common/fsfeatures.c | 8 + common/fsfeatures.h | 2 +- common/hmzoned.c | 590 ++++++++++++++++++++++++++++++++++++++ common/hmzoned.h | 90 ++++++ configure.ac | 13 + ctree.h | 21 +- disk-io.c | 10 + extent-tree.c | 15 + kerncompat.h | 2 + libbtrfsutil/btrfs.h | 2 + mkfs/common.c | 20 +- mkfs/common.h | 1 + mkfs/main.c | 107 +++---- transaction.c | 7 + volumes.c | 101 ++++++- volumes.h | 17 ++ 23 files changed, 1081 insertions(+), 70 deletions(-) create mode 100644 common/hmzoned.c create mode 100644 common/hmzoned.h -- 2.23.0
