Hi, Mitch
Could you test the third version of this patchset for me?
Thanks
Miao

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 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
You can merge this patchset to your "next" branch directly after dropping
the top four patches of the "next" branch.
Thanks
Miao

I've applied these patches to a 2.6.36 kernel that I've merged with
the patches on Chris' 'next' branch, and I'm getting a kernel error.
As per the instructions, I dropped the previous top four patches, and
applied patches 1-6 from this set of posts.
I am receiving this error while compiling boost on a 3.5 GB partition
formated with zlib compression.
I've replicated the error several times, so it's reproducible. Let me
know if you want to try something different to test.
I'm not seeing any corruption on this partition after rebooting, but
the partition locks up until a reboot.
This kernel was built for a single CPU.
