Uhuh, -16 is EBUSY so it seems Christian's block device opening changes are suspect? Do you have some sample kconfig available somewhere?

Thanks! So for record the config has:
CONFIG_BLK_DEV_WRITE_MOUNTED=y
So we are not hitting any weird corner case with blocking writes to mounted filesystems. It must be something else.
