[PATCH] MMC: Fix the block device read only flag

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



While the MMC handled the card's read only flag correctly on open,
it did not setup the flag in the allocated disk structure. The
consequence being that probing the /sys/class/block/mmcblkX/ro
attribute always reported 0.
