I would like to withdraw this patch.
Although it fixes the case of CONFIG_MMC_UNSAFE_RESUME=y
it doesn't fix the case of CONFIG_MMC_UNSAFE_RESUME=n
It is more like a workaround for real problem, problem that del_gendisk
hangs when it is called while userspace is frozen.
I bet that this is a regression.
