Before this patch, ext*_image is always set NODATACSUM inode flag.
However btrfs-convert will set normal file with DATACUSM flag by

Now, a regular file extent is shared by a btrfs file inode with DATACSUM

This will cause btrfsck complain about odd checksum, since ext*_image is

btrfs-progs: silence fake fsck
Harald suggested that we remove the message from the fake fsck.btrfs
that some distros run at boot:
https://bugzilla.redhat.com/show_bug.cgi?id=1206502
"This output does not add anything, but is a disturbing element of
booting up a system. It's the only message I get, when starting my
system, before gdm is started."
I'm inclined to agree.
This makes the tiniest change to remove the message that's output for an
auto invocation. My guess is that it was just copied from the xfs
fsck.xfs and that no one actually cares about it.

btrfs-progs: restore, fix page alignment issue for lzo compression
When runing restore under lzo compression, "bad compress length"
problems are encountered.
It is because there is a page alignment problem with the @decompress_lzo,
as follows:
|------| |----|-| |------|...|------|
page ^ page page
|
3 bytes left
When lzo pages are compressed in memory, we will ensure that the 4 bytes
length header will not cross a page boundary. There is a situation that
3 (or less) bytes are left at the end of a page, and then the 4 bytes
len is stored at the start of the next page. But the @decompress_lzo
doesn't go to the start of the next page and continue to read the next 4
bytes which crosses two pages, so a random value is fetched as a "bad
compress length".
So we check page alignment every time before we are going to fetch the
next @len and after the former piece of data is decompressed. If the
current page that we reach has less than 4 bytes left, then we should
fetch the next @len at the start of next page.

btrfs-progs: fsck-test: Add check_sudo to check valid root/sudo privilege
Although fsck-test/012 uses sudo, it uses 'sudo -n', which won't prompt
user to input password and will return 1 if no valid credential is
found.
And this makes test result quite annoying since it fails to mount and
still continue, which will always fail.
This patch will check 'sudo -v -n' and 'sudo -n true' to determine
whether sudo works fine in different version/settings, since in some
setting/version, 'sudo -v -n' will fail even the user is set NOPASSWD.
Also, remove the 'have_root_helper' variant, since there is a
possibility that sudo credential will timeout during the test and
'have_root_helper' won't help to detect such problem.
New '_sudo' command will do credential check if needed to avoid such

There is a case that can cause nlink fix function.
For example, lost+found dir already has the following files:
---------------------------

|-------------------------|
|258 |normal_file |
|259 |normal_file.260 |

The next inode to be fixed is the following:
---------------------------
|260 |normail_file |
---------------------------
And when trying to move inode to lost+found dir, its file name conflicts
with inode 258, and even add ".INO" suffix, it still conflicts with
inode 259.
Since the move failed, the LINK_COUNT_ERR flag is not cleared, the inode
record will not be freed, btrfsck will try fix it again and again,
causing the infinite loop.
The patch will first change the ".INO" suffix naming to a loop behavior,
and clear the LINK_COUNT_ERR flag anyway to avoid infinite loop.
