No need for the empty line.  Also I wonder if invalidate_disk might be a
better name - except for del_gendisk we don't really use _gendisk in
function names at all.

No need for the extern.  Also I'd name the argument disk, just as in
the actual implementation.

The actual functionality looks good to me despite these nitpicks.
