[PATCH V3 0/6] random bugfixes of the space management

[PATCH V3 0/6] random bugfixes of the space management

[Miao Xie]

Hello, Chris

I have a bunch of random fixes of the space management in

git://repo.or.cz/linux-btrfs-devel.git space-manage

They are the ENOSPC fixes, as well as fixes for df command.
The first one and the last one fixed the wrong free space information reported
by df command. The second one fixed ENOSPC when there is tiny space in the
filesystem. And The third fixed wrong calculation of stripe size. And the 4th
and 5th patches fixed the chunk allocation problem when the block devices have
no enough space to allocate a default-size chunk.

Changelog V2 -> V3:
- fix panic caused by freeing a invalid memory address.

Changelog V1 -> V2:
- fix compiler errors on x86_32 machines.
- fix some bugs when allocating dup chunks.
- break the chunk allocation when errors happen.
- just allocate min_stripes stripes when the free space is not enough.
- cleanup redundant code.

If you want to merge this patchset to your "next" branch for testing, you can merge it
directly after dropping the top four patches of the "next" branch.

Thanks
Miao

The problems I was encountering in the V2 version of this patch set
are fixed in V3.

Thanks for the updates.
