I might be missing something, but this doesn't actually push the BKL anyway. It adds duplicate BKL locking inside the ->open and ->release methods without actually removing it in the callers. That's a pretty pointless thing to do. If you're not feeling confident enough about touching block_dev.c I can look into that part of the pushdown, but this patch on it's own is not actually useful. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
