[PATCH] partitions: let partitions inherit policy from disk
[PATCH] partitions: let partitions inherit policy from disk

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.
