Although the cause for this sucks, I was actually going to suggest that
since 3.1 is a version bump, that we take the opportunity to change a
few defaults. Like switching to version 1 superblocks instead of
version 0 by default. And changing the default chunk size to 512k
instead of 64k. The time has simply come for the 0->1 superblock
change, and I have a good deal of data showing that for SATA disks at
least, the 512k chunk size is the typical sweet spot.
