The format of 'l' option in mkfs.btrfs.txt is wrong.
And, when the head of the character string is 65536, the following warning

Now, if exec:
# btrfs-debug-tree <mount_point>
it echos:
: Superblock bytenr is larger than device size
But it is quite misleading, because it is a valid btrfs.
In this case, we should tell the developer to provide a block device.
After apply:
: '<mount_point>' is not a block device

Commit 8be2fff (btrfs-progs: apply realpath for btrfs fi
show when mount point is given) changed the behavior of
btrfs fi show to return an error if the call to realpath()
failed. This broke the ability to specify a filesystem by
uuid or label.
So let's not consider a failed call to realpath() as an
error. If the user really specified a bad device, just
return nothing like we did before.

In reset_nlink(), we believe rec->found_link as accurate number of the
valid links. However it only records the number of found DIR_ITEM, so we
can't use it as reliable value.
Before this patch, in some case, leaf corruption recovery will believe
there is a valid backref but don't add_link() since it can't find any
valid one and don't put it into the lost+found dir.
So the recovered inode will be considered as an orphan item without
orphan item and repair_inode_orphan_item() will add orphan item for it,
causing all the filename/filetype we recovered being a waste of time.

When "/" is Btrfs, "btrfs property <subcommand> /" regards it
as non-root by mistake.
check_is_root() regards @object as a file system root if
the following two conditions are satisfied.
a) Both @object and its parent directory are Btrfs object
(file system root, subvolume, inode, and device
used for Btrfs).
b) fsid of the above mentioned two objects are different.
It doesn't work if @object is "/" because, in this case,
fsid of "/" and its parent (it's also "/"), are the same.
* Test environment
Two Btrfs file system (not subvolume) "/" and "/home/sat/mnt".
* How to reproduce
Submit "btrfs prop get" against the above mentioned file systems.
* Test Result
** Actual result (without my patch)
==========================
ro=false
label= # label is displayed because it's a file system root
ro=false # label is not displayed even if it's a file system root
==========================
** Expected result (with my patch)
==========================
ro=false
label=
ro=false
label=foo # label is displayed

This is because dev_size is defined as unsigned type, but lseek() will

This adds two new test images
1) 008-bad-offset-snapshots. This has a corrupt item with multiple snapshots
pointing to it, to make sure the bad block repair stuff doesn't loop and
actually repairs stuff. It also requires the dir index repair stuff to pass our
built in tests which is why it's not tied to the same commit.
2) 009-bad-dir-index-name.img. This has a corrupt name in a dir index to make
sure our dir index repair stuff is working properly.

There are options to specify if the subvolume deletion should wait for
