Introduce a block group type bit for a global reserve and fill the space info for SPACE_INFO ioctl. This should replace the newly added ioctl (01e219e8069516cdb98594d417b8bb8d906ed30d) to get just the 'size' part of the global reserve, while the actual usage can be now visible in the 'btrfs fi df' output during ENOSPC stress. The unpatched userspace tools will show the blockgroup as 'unknown'.
This wasn't in my rc2 pull because I wanted to sync up with Jeff on it. I like the idea of combining this into SPACE_INFO, any objections?
