Yes, but as far as I know, it's difficult for coccinelle to convert
the kfree() calls of any previous bitmap_alloc to bitmap_free as
most frequently the kfree() call is in a separate function.
Please do it if you know how, you're probably the best in the world
at coccinelle. I don't know how...
cheers, Joe
