Thanks, applied! The other two I already have a patch queued up for.

On i386 and x86_64, I also see this build problem:

drivers/md/bcache/bset.c:885:4: error: implicit declaration of function '__WARN' [-Werror=implicit-function-declaration]


Do you also have a patch for it?


thanks,

Nope - looks like __WARN() doesn't exist if CONFIG_BUG=n, whoops.

This problem still persists in linux-next as of today, how is this fix 
being pushed?

Sorry for the delay, I've been moving all last week - I just sent Jens a
pull request with the latest bcache fixes, though.
