Hello, I see a comment in the MMC block layer drivers/mmc/card/block.c that GENHD_FL_REMOVABLE should not be set for MMC block devices. How about the case of eMMC cards that are embedded on the chip. In that case, the eMMC card cannot be removed nor inserted and so the block device also cannot be removed. I guess eMMC falls under the case that it is a permanent block device and a permanent media. How should this be set for this case? Please correct me if I am wrong.
Mostly it is an issue with unsafe resume (see CONFIG_MMC_UNSAFE_RESUME) There is mmc_assume_removable module parameter (see drivers/mmc/core/core.c) And there is the mmc_host capability flag MMC_CAP_NONREMOVABLE (see include/linux/mmc/host.h)
