Hello,
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
Josef has implemented mixed data/metadata chunks, we must add those chunks'
space just like data chunks.

We cannot write data into files when when there is tiny space in the filesystem.
Reproduce steps:
# mkfs.btrfs /dev/sda1
# mount /dev/sda1 /mnt
# dd if=/dev/zero of=/mnt/tmpfile0 bs=4K count=1
# dd if=/dev/zero of=/mnt/tmpfile1 bs=4K count=99
(fill the filesystem)
# umount
- make it return the start position and length of the max free space when it can
not find a suitable free space.
- make it more readability

There are two tiny problem:
- One is When we check the chunk size is greater than the max chunk size or not,
we should take mirrors into account, but the original code didn't.
- The other is btrfs shouldn't use the size of the residual free space as the
length of of a dup chunk when doing
When we store data by raid profile in btrfs with two or more different size
disks, df command shows there is some free space in the filesystem, but the
user can not write any data in fact, df command shows the wrong free space
information of btrfs.
# mkfs.btrfs -d raid1 /dev/sda9 /dev/sda10

Hi,
this patch seems to have the same intention as the patch I sent to the
list on Dec 11 Fixing the chunk allocator to allow it to better
utilize the devices. The result is quite similar, except that you
left the line
search_start = max(root-fs_info-alloc_start, search_start);
in place, which
