Hell, I experienced a bug after upgrading to a recent kernel (4.5.0). # echo /dev/md2 > /sys/fs/bcache/register gives me a stack trace. I created a bug in the kernel bugtracker but I'm not sure if it has been noticed by the bcache developers: <https://bugzilla.kernel.org/show_bug.cgi?id=114871> Could somebody have a look?
