IMO, used should definitely include metadata, especially given that we
inline small files.
I can convince myself both that this implies that we should roll it
into b_avail, and that we should go the other way and only report the
actual used number for metadata as well, so I might just plead
insanity here.
I could be convinced to do this. So we have
total: (total disk bytes) / (raid multiplier)
used: (total used in data block groups) +
(total used in metadata block groups)
avail: total - (total used in data block groups +
total metadata block groups)
That seems like the simplest to code up. Then we can argue about
whether to use the total metadata size or just the used metadata size
for b_avail. Seem reasonable?
