additional partition_data* child parameter now.
* _user_get_partitionable_spaces() doesn't need to copy the buffer into
the kernel, since it is no input parameter. It also copies back the
actual partitionable spaces count on error, now -- B_BUFFER_OVERFLOW
is returned when the buffer was too small, but then the count must be
returned too.
* Fixed several instances of syscall implementations that unloaded a disk
system, although they didn't load it in the first place. This screwed
up the load count with undesirable consequences.
* _user_create_child_partition() would set the size to the supplied
offset.
* Fixed broken loop in KPhysicalPartition::CreateShadowPartition().
* KPartition::RemoveChild() notified the listeners about the wrong
event.
* Intel partitioning module:
- The *_get_partitionable_spaces() correctly return B_BUFFER_OVERFLOW
now, if the supplied buffer is too small.
- Implemented a part of pm_shadow_changed(), which creates and updates
the PartitionMap, so that the validate_*() hooks have a chance to
work at all.
