Subject: [PATCHSET 5/9] fuse2fs: refactor mount code

Hi all,

Here, we hoist the mounting code out of main() into a pile of separate
helper functions to reduce the complexity of understanding the mount
code.  This isn't strictly required for iomap, but it makes main() a lot
easier to understand.

If you're going to start using this code, I strongly recommend pulling
from my git trees, which are linked below.

Comments and questions are, as always, welcome.
