[PROBLEM]
Since we have migrated to default v2 cache, the test case
misc/030-missing-device-image is no longer executed:
[TEST/misc] 030-missing-device-image
[NOTRUN] unable to create v1 space cache
[CAUSE]
The test case itself is trying its best to cover all paths, including
the data extent read path.
Thus the test case is requiring v1 cache, as that's the only way to
cover the data read path.
[FIX]
Just remove the v1 space cache requirement, it's still better to run the
test even it only exercises the metadata read path.
The good news is, after commit 3ff9d35257 ("btrfs-progs: use
read_data_from_disk() to replace read_extent_from_disk() and replace
read_extent_data()"), all data/metadata read paths are unified.
They only difference is the verification part.
Thus even if we didn't fully exercise the data read path, we didn't lose
much coverage anyway.

[BUG]
During my test runs of mkfs-tests, 005-long-device-name-for-ssd failed
with the following error messages:
====== RUN CHECK dmsetup remove btrfs-test-with-very-long-name-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAQPGc
device-mapper: remove ioctl on btrfs-test-with-very-long-name-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAQPGc failed: Device or resource busy
Command failed.
failed: dmsetup remove btrfs-test-with-very-long-name-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAQPGc
test failed for case 005-long-device-name-for-ssd
[CAUSE]
There seems to be a race between "btrfs inspect dump-super" and the
dmsetup removal.
[FIX]
Add a "udevadm settle" before removing the dm devices.
Also since we're here, use the same "udevadm settle" instead of the
manual sleep to wait for the new dm device to show up.

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.

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

Now we can use newlines in option descriptions to make nicer lists for
options:
--sort MODE sort by a column ascending (default: pstart),
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

variable INJECT. For now a single value is accepted.
Use like:
if (inject_error(0x1234)) {
do_something();
return -ERROR;
}

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.
