Thanks for the enlightenment! I'll leave bigalloc aside for this usage,
but I'll definitely keep it around for another use case that I wanted to
submit to the list (in a later message).

Thanks a lot, this is much helpful. It confirms my intent to go for a 2M
bytes-per-inode ratio so as to reach ~460k inodes (or twice as much as
I'll probably need).
