Since '--sort' options was given ,and we can list snapshots in generation
order by --sort=+/-gen to replace '-s [0|1]' totally.

We list the subvolumes under current directory according to the input
subvolume.
However, if we still want to list all the subvolumes in the tree, we
can use '-a' option to help us.
There may be two kinds of path: absolute path , relative path .
The absolute path is beginning with "<FS_TREE>"
The relative path is under current path that you input.

This patch introduces '-g' '-c' '--sort' options
The option '-g' can help you filter the subvolumes by the generation, you may
use it just like:
btrfs subvol list -g +/-value <path>
'+' means the generation of the subvolumes should >= the value you specified.
'-' means the generation should <= the value
If you don't input either '+' nor '-', this command will list the subvolumes
that their generation equals to the value.
However if you want to find gengeration between value1 and value2
you may use the above like:
btrfs sub list -g -value1 -g +value2 <path>
The option '-c' can help you filter the subvolumes by the ogeneration, you may
use it just like:
btrfs subvol list -c +/-value <path>
The usage is the same to '-g'
You might want to list subvolumes in order of some items, such as root id, gen
and so on, you can use '--sort'. Now you can sort the subvolumes by root id,
gen, ogen and path.
For example:
If you want to list subvolumes in order of rootid, you can use the option like
that:
btrfs sub list --sort=+/-rooid <path>
Here, '+' means the result is sorted by ascending order. '-' is by descending
order. If you don't specify either '+' nor '-', the result is sorted by
default - ascending order.
If you want to combine sort items, you do it like that:
btrfs sub list --sort=-rootid,+path,ogen,gen <path>

Usage of balancing btrfs is "btrfs filesystem balance",
not "btrfs device balance". And remove unneeded
usage of "btrfs filesystem defrag".
Also fix some typos and over 80 columns.

The btrfs filesystem resize command defaults to only resizing the
filesystem for devid 1, and must have a devid passed in to resize the
filesystem for the other devices in the filesystem.
Additionally the documentation lacked information on how to actually
resize the underlying partition so this provides a little more detail.

During the commands:
- btrfs filesystem show
- btrfs device scan
the devices "scanned" are extracted from /proc/partitions. This
should avoid to scan devices not suitable for a btrfs filesystem like cdrom
and floppy or to scan not existant devices.
The old behavior (scan all the block devices under /dev) may be
forced passing the "--all-devices" switch.

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

Hi all,
enclose you can find a patch which improves the help of the btrfs commands,
updates the INSTALL file and the btrfs (command) man page.
Regarding the help of the btrfs command:
- moved the "subvolume set-default" command in the "subvolume" commands group
- removed a wrong new line
- small tweak on the basis of Andreas suggestion
Regarding the btrfs command man page:
- renaming the command "device balance" in "filesystem balance" (thanks to
Andreas Phillipp to highlight that)
- adding the entry "subvolume find-new"
- document the switches of the command "filesystem defrag"
- document the <devid> facility of the command "filesystem resize"
- small tweak on the basis of Andreas suggestion
Regarding the INSTALL file, which was very old, I removed the reference of the
old btrfsctl utility and changed the examples using the btrfs command.
I removed the old (and now wrong) statement about the inability to delete a
subvolume/snapshot
Chris, you can pull the patch from the branch "help_cleanup" of the following
repository.
http://cassiopea.homelinux.net/git/btrfs-progs-unstable.git
(or you can browse the changes at
http://cassiopea.homelinux.net/git/btrfs-progs-unstable.git/?p=btrfs-
progs-unstable-all.git;a=summary)
The patch is very simple: only updates the man page, the INSTALL file and
moves/updates some lines in the help of btrfs command. Comments are welcome.
Regards
G.Baroncelli

[Btrfs-Progs][V2] Update for lzo support
- Add incompat flag, otherwise btrfs-progs will report error
when operating on btrfs filesystems mounted with lzo option.
- Update man page.
- Allow to turn on lzo compression for defrag operation:
# btrfs filesystem defragment -c[zlib, lzo] <file>
Note: "-c zlib" will fail, because that's how getopt() works
for optional arguments.
