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