Hmm, calling the current code crap is not exactly confidence inspiring for running 3.11 or 3.12 in production ;). If you're in an email answering mood, any chance I could trouble you to answer the question I posed earlier this week about the -w option to make-bcache, its relation (or not) to SSD page size, and how to best configure an SSD with a page size of 8k as a cache device :)? Thanks.
