[PATCH 0/9] btrfs-progs: convert: fix a long bug that bgt feature never works

[Qu Wenruo <wqu@suse.com>]

There is a long bug that, "btrfs-convert -O bgt" doesn't create a fs
with bgt feature at all.

In fact "mkfs.btrfs -O bgt" is no different than "mkfs.btrfs -O ^bgt".

The root cause is explained and fixed in the second last patch.

The first 7 patches are mostly preparation and cleanup for properly
intorduce block group tree at temprory fs creation time.

Qu Wenruo (9):
  btrfs-progs: convert: add feature dependency checks for bgt
  btrfs-progs: convert: replace the bytenr check with a UASSERT()
  btrfs-progs: convert: simplify insert_temp_root_item()
  btrfs-progs: convert: simplify insert_temp_dev_item() and
    insert_temp_chunk_item()
  btrfs-progs: convert: simplify insert_temp_dev_extent()
  btrfs-progs: convert: simplify insert_temp_extent_item() and
    insert_temp_block_group()
  btrfs-progs: convert: merge setup_temp_fs_tree() and
    setup_temp_csum_tree()
  btrfs-progs: convert: implement the block group tree support properly
  btrfs-progs: convert-tests: add a test case for bgt feature
