Change the partition code in fs/partitions/check.c to initialize a newly detected partition's policy field with that of the containing block device (see patch below). My reasoning is that function set_disk_ro() in block/genhd.c modifies the policy field (read-only indicator) of a disk and all contained partitions. When a partition is detected after the call to set_disk_ro(), the policy field of this partition will currently not inherit the disk's policy field. This behavior poses a problem in cases where a block device can be 'logically de- and reactivated' like e.g. the s390 DASD driver because partition detection may run after the policy field has been modified.
