8b4e3d8b5b Btrfs-progs: implement new subcommand parser
This completely replaces the existing subcommand infrastructure, which
is not flexible enough to accomodate our needs.  Instead of a global
command table we now have per-level tables and command group handlers,
which allows command-group-specific handling of options and subcommands.
The new parser exports a clear interface and gets out of the way - all
control over how matching is done is passed to commands and command
group handlers.

One side effect of this is that command implementors have to check the
number of arguments themselves - patch to fix up all existing commands
follows.

e8f47cf068 Add the "btrfs filesystem label" command
Hi all,

this patch adds the command "btrfs filesystem label" to change (or show) the
label of a filesystem.
This patch is a subset of the one written previously by Morey Roof. I
included the user space part only. So it is possible only to change/show a
label of a *single device* and *unounted* filesystem.

The reason of excluding the kernel space part, is to simplify the patch in
order to speed the check and then the merging of the patch itself. In fact I
have to point out that in the past there was almost three attempts to propose
this patch, without success neither complaints.

Chris, let me know how you want to proceed. I know that you are very busy,
and you prefer to work to stabilize btrfs instead adding new feature. But I
think that changing a label is a *essential* feature for a filesystem
managing tool. Think about a mount by LABEL.

To show a label

$ btrfs filesystem label <device>

To set a label

$ btrfs filesystem label <device> <newlabel>

Please guys, give a look to the source.
Comments are welcome.

You can pull the source from the branch "label" of the repository

b4382217f1 Btrfs-progs: add a btrfs-select-super command to overwrite the super
Btrfs stores multiple copies of the superblock, and for common power-failure
crashes where barriers were not in use, one of the super copies is often
valid while the first copy is not.

This adds a btrfs-select-super -s N /dev/xxx command, which can
overwrite all the super blocks with a copy that you have already
determined is valid with btrfsck -s

6d2cf04247 new util: 'btrfs'
This commit introduces a new command called 'btrfs' for managing
a btrfs filesystem. 'btrfs' handles:
- snapshot/subvolume creation
- adding/removal of volume (ie: disk)
- defragment of a tree
- scan of a device searching a btrfs filesystem
- re-balancing of the chunk on the disks
- listing subvolumes and snapshots

This has also been updated to include the new defrag range ioctl.

95d3f20b51 Mixed back reference (FORWARD ROLLING FORMAT CHANGE)
This commit introduces a new kind of back reference for btrfs metadata.
Once a filesystem has been mounted with this commit, IT WILL NO LONGER
BE MOUNTABLE BY OLDER KERNELS.

The new back ref provides information about pointer's key, level and in which
tree the pointer lives. This information allow us to find the pointer by
searching the tree. The shortcoming of the new back ref is that it only works
for pointers in tree blocks referenced by their owner trees.

This is mostly a problem for snapshots, where resolving one of these fuzzy back
references would be O(number_of_snapshots) and quite slow.  The solution used
here is to use the fuzzy back references in the common case where a given tree
block is only referenced by one root, and use the full back references when
multiple roots have a reference
