SubjectRe: [PATCH][2.5] Fix block backed loop mounts
	Thank you for picking up this patch and resubmitting it.  I
don't think anyone had any complaints about it before. I was
wondering if it had fallen through the cracks. Jens, do you want to
integrate this patch into whatever you are sending to Linus, or should
Zwane or I needle Linus directly about it?
