- update to version 4.20
  * new feature: metadata uuid
    * lightweight change of UUID without rewriting all metadata
      (incompatible change)
    * done by btrfstune -m/-M, needs kernel support, 5.0+ 
  * image:
    * fix block groups when restoring from multi-device image
    * only enlarge result image if it's a regular file 
  * check
    * more device extent checks and fixes 
  * can repair dir item with mismatched hash
  * mkfs: uuid tree created with proper contents
  * fix mount point detection due to partial prefix match
  * other:
    * new tests, build fixes, doc updates
    * libbtrfsutil: fix tests if kernel lacks support for new
      subvolume ioctls

From c4aadd9af2d153a03cda59977ed9a7d5700d9eae Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/6] btrfs-progs: Add support for metadata_uuid field
Add support for a new metadata_uuid field. This is just a preparatory
commit which switches all users of the fsid field for metdata comparison
purposes to utilize the new field. This more or less mirrors the
kernel patch, additionally:
* Update 'btrfs inspect-internal dump-super' to account for the new
field. This involes introducing the 'metadata_uuid' line to the
output and updating the logic for comparing the fs uuid to the
dev_item uuid.

Subject: [PATCH 2/6] btrfs-progs: btrfstune: Add support for changing the user
uuid
This allows us to change the use-visible UUID on filesytems from
userspace if desired, by copying the existing UUID to the new location
for metadata comparisons. If this is done, an incompat flag must be
set to prevent older filesystems from mounting the filesystem, but
the original UUID can be restored, and the incompat flag removed.
This introduces the new -m|-M UUID options similar to current
-u|-U UUID ones with the difference that we don't rewrite the fsid but
just copy the old uuid and set a new one. Additionally running with
[-M old-uuid] clears the incompat flag and retains only fsid on-disk.
Additionally it's not allowed to intermix -m/-u/-U/-M options in a
single invocation of btrfstune, nor is it allowed to change the uuid
while there is a uuid rewrite in-progress. Also changing the uuid of a
seed device is not currently allowed (can change in the future).
Example:
btrfstune -m /dev/loop1
btrfs inspect-internal dump-super /dev/loop1
superblock: bytenr=65536, device=/dev/loop1
---------------------------------------------------------
csum_type 0 (crc32c)
csum_size 4
csum 0x4b7ea749 [match]
<ommitted for brevity>
fsid 0efc41d3-4451-49f3-8108-7b8bdbcf5ae8
metadata_uuid 352715e7-62cf-4ae0-92ee-85a574adc318
<ommitted for brevity>
incompat_flags 0x541
( MIXED_BACKREF |
EXTENDED_IREF |
SKINNY_METADATA |
METADATA_UUID )
<omitted for brevity>
dev_item.uuid 0610deee-dfc3-498b-9449-a06533cdec98
dev_item.fsid 352715e7-62cf-4ae0-92ee-85a574adc318 [match]
<ommitted for brevity>
mount /dev/loop1 btrfs-mnt/
btrfs fi show btrfs-mnt/
Label: none uuid: 0efc41d3-4451-49f3-8108-7b8bdbcf5ae8
Total devices 1 FS bytes used 128.00KiB
devid 1 size 5.00GiB used 536.00MiB path /dev/loop1
In this case a new btrfs filesystem was created and the original uuid
was 352715e7-62cf-4ae0-92ee-85a574adc318, then btrfstune was run which
copied that value over to metadata_uuid field and set the current fsid
to 0efc41d3-4451-49f3-8108-7b8bdbcf5ae8. And as far as userspace is
concerned this is the fsid of the fs.

From 1a438fc67c6b389221f20e25c13acd195fa0656b Mon Sep 17 00:00:00 2001
From: Nikolay Borisov <nborisov@suse.com>
Date: Thu, 11 Oct 2018 18:04:03 +0300
Subject: [PATCH 4/6] btrfs-progs: Remove btrfs_fs_info::new_fsid
This member was used only by btrfstune when using the old method to
change fsid. It's only an in-memory value with a very specific
purpose so it makes no sense to pollute a generic structure such as
btrfs_fs_info with it. Just remove it and pass it as a function
argument where pertinent. No functional changes.
