  [112.497834] BTRFS error (device sdb2): failed to read chunk tree: -2
  [112.507705] BTRFS error (device sdb2): open_ctree failed

The original fsid created by mkfs was a6599a65-8b6d-4156-bb55-0a3a2f0eae9d,
and the fsid created by the btrfstune -m option was
1b3bacbf-14db-49c9-a3ef-547998aacc4e.

During mount (after btrfstune -m), only 3 out of 8 devices were scanned
by systemd, while the rest were still being discovered. Consequently, the
mount command raced to find the missing devices. Since the mount command
in the kernel sets the flag fsdevices::opened, any further new alloc_device()
were blocked, resulting in the error "the fs is already mounted."

It is a good idea to register all devices after changing the fsid.
The previous registrations are already stale after changing the fsid.

cac019e583 btrfs-progs: list-chunks: update column names
Make the column names more descriptive, PNumber is from times when there
was only physical sort. Make the type/profile more explicit, later it
can be filtered by that. The 'Age' reflects the current allocation
strategy to always pick a higher number but this could become confusing,
it's really the number when sorted by logical offset.

Now we can use newlines in option descriptions to make nicer lists for
options:

                              MODE can be one of:
                              pstart - physical offset, grouped by device
                              lstart - logical offset
                              usage - by chunk usage (implies --usage)
                              length_p - by chunk length, secondary by physical offset
                              length_l - by chunk length, secondary by logical offset

6f05548661 btrfs-progs: add error injection helper script
Add a convenience script for adding new injection cookies and filter for
actual testing.

- ./inject-error new - return new unique cookie
- ./inject-error file tune/change-csum.c - show all cookies in the given
  file (takes regexp)

Example usage:

  for i in $(./inject-error file tune/change-csum.c | awk '{print $1}') ; do
	  echo "Inject $i"
	  export INJECT="$i"
	  rm img
	  cp --reflink img.filled img
	  ./btrfstune --csum blake2 img
	  btrfs check img
  done

Where 'img' is a filesystem with sample files and directories.

8922ab5d6a btrfs-progs: add simple error injection framework
To be able to test errors at specific locations, add a simple way to
check for a condition in code and controlled from user space environment
variable INJECT. For now a single value is accepted.

Use like:

	if (inject_error(0x1234)) {
		do_something();
		return -ERROR;
	}

This is enabled in debugging build by default (make D=1) and can be
enabled on demand too (make EXTRA_CFLAGS=-DINJECT).

This is because `pread()` behaves differently on aarch64 and sets
`errno = 2` instead of the usual `errno = 0`.

To fix check if the sb offset is beyond the device size or regular file
size and skip the corresponding sbread().

Also, move putchar('\n') after a successful call to load_and_dump_sb() to
the load_and_dump_sb() itself.

8da82cde9c btrfs-progs: dump-super: drop the label out and variable ret
In cmd_inspect_dump_super(), at the label 'out', nothing much happens
other than returning ret.

At the goto statement to the label, in the for loop, we perform close(fd).
However, moving the close(fd) to 'out' as well is not a good idea because
close(fd) doesn't make sense outside the for loop.

Instead, simply return 1 instead of ret=1 and then returning it. Drop both
the 'out' label and ret.

b51117d68e btrfs-progs: tests: check for btrfs ACL support
Fix failures caused by the lack of ACL support in btrfs. For example:

  $ make test
    ::
    [TEST/misc]   057-btrfstune-free-space-tree
    failed: setfacl -m u:root:x /Volumes/ws/btrfs-progs/tests/mnt/acls/acls.1
    test failed for case 057-btrfstune-free-space-tree
    make: *** [Makefile:493: test-misc] Error 1

Similar failures occurred in the test cases convert/001-ext2-basic,
convert/003-ext4-basic, convert/005-delete-all-rollback, and
convert/006-large-hole-extent.

Resolve it by adding a check for ACL support using the
check_kernel_support_acl() helper function. It gracefully handles the case
when ACL support is not compiled by calling _not_run().
