[v5,00/15] btrfs-progs: zoned block device support

Message

Naohiro Aota Dec. 4, 2019, 8:24 a.m. UTC

This is a userland part of supporting zoned block device on btrfs.

Since the log-structured superblock feature changed the location of
superblock magic, the current util-linux (libblkid) cannot detect
HMZONED btrfs anymore. You need to apply a to-be posted patch to
util-linux to make it "zone aware".

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: support discarding zoned device
  btrfs-progs: support zero out on zoned block device
  btrfs-progs: implement log-structured superblock for HMZONED mode
  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
