It's pointless to switch and trace partition type if the current selected device partition is the same with that one. Moreover, cycled claiming host associated with mmc_blk_part_switch() could make mmc_blk_remove() end up waiting for grabbing the context if it's occupied, which lead requests could still hit the low-level drivers, if an asynchronous unbind for host drivers happened, as the card hasn't been set removed in the remove path. So a simple dd in background: dd if=/dev/mmcblk0 of=/dev/null bs=512k count=100000 & and doing unbind then: echo fe320000.dwmmc > /sys/bus/platform/drivers/dwmmc_rockchip/unbind could make the console stuck for quite a while depending on the numbers of requests.
