It pushes the BKL down into the i2c driver. The intention is to remove the big kernel lock ioctl method from the file_operations structure so that we can work on getting rid of the big kernel lock for good. It's one of a series of patches that give me an x86-32 tree with no ->ioctl method at all.
Similar activity is going on for the other calls made under the BKL the goal being to push it down into drivers and then eliminate it.
