I'm not huge fan of the container_of() redundancy, but adding private variants of this doesn't seem like the best way forward. Let's have a generic helper that does this, and use it everywhere. -- Jens Axboe _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
