Comment (by pulkomandy):
This code is used each time you mount a volume. You do not know where the
volume comes from, maybe it was freshly formatted by mkfs, or maybe it is
from an USB stick coming from another computer.
According to https://btrfs.wiki.kernel.org/index.php/Manpage/mkfs.btrfs,
the node size even changed accross btrfs versions, and both the node and
sector size depend on the page size of the machine the FS was created on.
So, if one carries a filesystem from one system to another (USB stick, or
just booting different OS on the same machine), or keeps an old filesystem
next to a newer one, you can easily end up with filesystems of different
block sizes. We need to handle that correctly.
