Message

Naohiro Aota Aug. 20, 2019, 4:52 a.m. UTC

This is a userland part of zoned block device support for btrfs.

Kernel side patch series:
https://lore.kernel.org/linux-btrfs/[e-mail]/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.
