Previous patch detecs inconsistency and unconditionally triggers quota
rescan. This may not be always desired as it's a heavy metadata
operation. In case of batch assignments it's better to trigger the
rescan at the end.

Currently there is not way for a user to know what is the minimum size a
device of a btrfs filesystem can be resized to. Sometimes the value of
total allocated space (sum of all allocated chunks/device extents), which
can be parsed from 'btrfs filesystem show' and 'btrfs filesystem usage',
works as the minimum size, but sometimes it does not, namely when device
extents have to relocated to holes (unallocated space) within the new
size of the device (the total allocated space sum).
This change adds the ability to reliably compute such minimum value and
extents 'btrfs filesystem resize' with the following syntax to get such
value:
btrfs filesystem resize [devid:]get_min_size

So far the subvol sync command takes a shortcut and looks if there are
any deleted subvols at all. It does not print the deleted subvolumes as
they get cleaned. Arguably this is what the user would like to see and
has to do
$ btrfs subvol sync /path $(btrfs subvol list -d /path | "extract the ids")
to see the progress.
Make it look for all currently deleted subvolumes automatically and
print the progress as if the ids were listed manually.
This is a slight change in the semantics of the command. Previously, any
new subvol deletion would prevent subvol sync to return. To simulate the
old behaviour, run 'subvol sync' in a loop until it returns 0.

In a chroot environment we may not have /proc mounted, which makes btrfs receive
freak out since it wants to know the base directory where are are mounted for
things like clone and such. Give an option to specify where the mountpoint is
in these cases so you can still do a btrfs receive in a chroot. Thanks,

Although btrfs-convert can rollback converted btrfs, it still has some
limitation to ensure rollback.
Add a warning on the limitations.
Also add a note for users who decides to go on with btrfs and don't need

Fixes various formatting issues:
Fixes quoting issues in various manpages. Before/After excerpts for
mkfs.btrfs(8), btrfs-qgroup(8):
mkfs.btrfs [-A|--alloc-start '<alloc-start>']
mkfs.btrfs [-A|--alloc-start <alloc-start>]
id 0/<subvolume id>''
id 0/<subvolume id>
If multiple '<attr>'s is given, use comma to separate.
If multiple <attr>s is given, use comma to separate.
The one that is most apparent is the removal of text in
btrfs-subvolume(8) and others. Before/After:
list [options] [-G <value>] [-C <value>] [--sort=rootid,gen,ogen,path] <path>
list [options] [-G [+|-]<value>] [-C [+|-]<value>] [--sort=rootid,gen,ogen,path] <path>
create [-i <qgroupid>] <name>
create [-i <qgroupid>] [<dest>]<name>
This happens because `<foo>` was replaced by `'<foo>'` in the sed
expression, which is then treated as a constrained quote. As a result,
the `[...]` before the string gets interpreted as "quoted text
attributes".
In this patch, the sed expression is dropped and asciidoc is configured
to recognize `<...>` as a unconstrained quoted string (such that
`<attr>s` is correctly emphasized) and to avoid adding quotes in
contexts where it is not needed.
A remaining problem is that some texts (the one between brackets) do not
add the emphasis for `<...>`. While this could be solved by replacing
`[` and `]` with `[` and `]` using sed, it introduces formatting
problems in btrfs-zero-log(8) because the context is ignored.
