This patchset will address the github issue #123 to make btrfs-convert
less possible to report false ENOSPC.
The first patch will try to avoid the nested chunk/extent tree
modification in a more explicit way.
The 2nd patch will address the ENOSPC problem, by adding CSUM tree to
the metadata preallocate list.
The 2nd patch is not as aggressive as 7a12d8470e5f ("btrfs-progs:
Do metadata preallocation as long as we're not modifying extent tree").
Even we have the 1st patch I still prefer to make less modification to
avoid possible bugs.
Qu Wenruo (2):
btrfs-progs: Avoid nested chunk allocation call
btrfs-progs: Do metadata preallocation for fs trees and csum tree
