I pulled your 'bcache-for-staging' code into a 'dm-devel-cache-bcache' branch on my github:
Purpose is to have a single kernel to compare dm-cache and bcache. My branch is against 3.8-rc2. While importing your code I needed the following change to get bcache to compile:
It now builds without issue but I haven't tested the resulting bcache to know if I broke the sysfs interface due to s/cache/bcache/ on some local variables, I don't think I did but I'll defer to you. (BTW those crafty sysfs macros you have were pretty opaque; not really seeing what they buy in the grand scheme. And #include "sysfs.c" is different than any code I've seen in the kernel).
