In command btrfs subvolume set-default, we used subvolume id and path
to set the default subvolume of a filesystem. It's not easy for a common
user, so I improved it and the fullpath of a subvolume can be used to
set the default subvolume of a filesystem.

What is not easy? How often do you set
Btrfs's command help system allow you to show only one line short usage.
But in some case we need to use two or more lines to show
the short usage of a complicated command.
This patch add a filed 'lines' in cmd_struct, which is the number of the
extra short usage lines you want to append.

This patch introduces another form of btrfs subvolume set-default command.
In command btrfs subvolume set-default, we used subvolume id and path
to set the default subvolume of a filesystem.
By the new form, we can use subvolume path to set the default subvolume.
The new form:
subvolume
When open_ctree(device, ...) failed, the return value should be checked.

when send/receive a sparse file, the holes of the original file
will be filled with zero. The holes will be sent as ZERO streams,
and it's unnecessary.
So, I improved this by skipping the hole of file while sending.

In cmd_send_start(), there is a check to make sure dump_fd is not a tty
before parsing command options. So if we use the option -f file,
it doesn't work for the dump_fd has not been created. So fix it.

Good catch, thanks. I see
It is very difficult for me to find any good documentation on send receive
commands. Event the most recent btrfs progs man page (accessed from git

I want to migrate data (including numerous read only snaphots) from
linux-raid - based storage into a native raid
