BTW - probably the most valuable thing you could help out with is the
documentation, in particular the guide:
http://bcache.evilpiepirate.org/BcacheGuide/

Can you read through (at least some of) that, and tell me what's useful and what
needs clarifying? And tell me what you'd like to see added to the guide next -
I'll try and work on documentation over the next two weeks, since I probably
won't be able to do much real coding with my test machines offline.

Yes, I'll read through that.

Would you add some example to explain how the extents/inodes/dirents are stored
in the btree on disk?

I'm reading the debug code in drivers/md/bcache/debug.c.
It seems helpful to learn about the internal btree structure.

Thanks.
