[PATCH 0/6] btrfs-progs: zoned devices support for bgt feature

There is a bug report that, the following tool would fail on zone
devices:

- mkfs.btrfs -O block-group-tree
- btrfstune --convert-to-block-group-tree|--convert-from-block-group-tree

The mkfs failure is caused by zoned incompatible pwrite() calls for
block group tree metadata.

The btrfstune failure is caused by the incorrectly opened fd.


Before fixing both bugs, do two small cleanups, one caught by clangd LSP
server, the other caught by my later check on the test case output (a
missing newline).

Then fixes for each bug, and new test cases for each bug.

Qu Wenruo (6):
  btrfs-progs: remove unused header for tune/main.c
  btrfs-progs: tune: add the missing newline for
    --convert-from-block-group-tree
  btrfs-progs: mkfs: use proper zoned compatible write for bgt feature
  btrfs-progs: tune: properly open zoned devices for RW
  btrfs-progs: tests-mkfs: add test case for zoned block group tree
    feature
  btrfs-progs: tests-misc: add a test case to check zoned bgt conversion
