[PATCH 0/3] btrfs-progs: mkfs: make sure we can clean up all temporary chunks

[Qu Wenruo <wqu@suse.com>]

There is a bug report that with certain mkfs options, mkfs.btrfs may
fail to cleanup some temporary chunks, leading to "btrfs filesystem df"
warning about multiple profiles:

  WARNING: Multiple block group profiles detected, see 'man btrfs(5)'.
  WARNING:   Metadata: single, raid1 

The easiest way to reproduce is "mkfs.btrfs -f -R free-space-tree -m dup
-d dup".

It turns out that, the old _recow_root() can not handle tree levels > 0,
while with newer free space tree creation timing, the free space tree
can reach level 1 or higher.

To fix the problem, Patch 2 will do the proper full tree re-CoW, with
extra transaction commitment to make sure all free space tree get
re-CoWed.

The 3rd patch will do the extra verification during mkfs-tests.

The first patch is just to fix a confusing parameter which also caused
u64 -> int width reduction and can be problematic in the future.

    chunks
