but it is mandatory to the KDiskSystem::ValidateCreateChild(), which is
invoked, so we need to use a stack variable.

physical partition, unlike get_partition() which returns the shadow
partition, if it exists.
* Added B_PARTITION_SHADOW[_CHILD] partition pseudo operation values for
the shadow_changed() hook, notifying a disk system, that a shadow
partition has been created.

BPartition structure with the data retrieved from the kernel. For new
partitions the field is not set in the next step and later code would
use an initialized pointer.

parent (not the child) partition, now. A method with the old semantics
is probably needed, too, but before creating a child partition, one
obviously doesn't have a child to pass yet.

allocate with the vm_cache locked - this is necessary to be able to steal pages
from itself (large files...).
The system doesn't actually lock up anymore, but it still renders itself unusable;
obviously the page thief does not work correctly, yet. The rest of the experience
is created by our current scheduler (the page thief runs and runs, but it doesn't
free any pages anymore).

twice into the same cache: cache_io() called read_into_cache() (or
write_to_cache()), and that broke down the request into smaller parts.
It then called read_chunk_into_cache() (or write_chunk_to_cache() resp.)
to actually allocate pages and fulfill the request.
However, it needed to unlock the cache for each chunk, and in the mean
time someone else could insert pages into the remaining chunks.
* Now, cache_io() already takes care of chunking the data which makes this
approach safe, and also simplified the code a bit - read_into_cache()/
write_to_cache() are gone now. I've renamed read_chunk_into_cache() to
read_into_cache() (same for the write function).
* Also got rid of that goto in that function while I was on it.
* Disabled cache_prefetch_vnode() for now (it's similar to cache_io(), but
since it's currently not used [since no cache module is installed yet],
I didn't want to go through updating it now, too).

it yet, but we'll certainly see :-)

interfere with the page thief, we always need to have reserved a page for
this upfront. I introduced a function to the vm_translation_map layer that
estimates how much pages a mapping might need at maximum. All functions that
map a page now call this and reserve the needed pages upfront.
It might not be a nice solution, but it works.
* The page thief could run into a panic when trying to call vm_cache_release_ref()
on a non-existing (NULL) cache.
* Also, it will now ignore wired active pages.
* There is still a race condition between the page writer and the vnode
destruction - writing a page back needs a valid vnode, but that might just
have been deleted.

mjw for the hint. Fixes bug #1516.
* Changed _{kern,user}_create_symlink() to no longer check the supplied
link string. BeOS seems to do that, but this is not standard
conforming. The previous implementation even used the path processed
by check_path(), which would potentially have appended a ".".
* Some style cleanup.

now.

system initialize() hooks. It's often the only info about the
partition one needs and thus locking the partition just to get it is
no longer necessary.
* intel partitioning system:
- Removed passing around block sizes. We require 512 byte sectors
anyway. In fact using the parent partition's block size was even
wrong.
- Simplified writing the partition map sector.
- Simplified and corrected the partition map initialization.
- We don't fail identifying a partition anymore, if the partition map
contains no partitions. We would never identify a freshly
initialized partition map before.
- Made pm_identify() more intelligent: It determines the priority to
return depending on whether the partition is the device itself and
whether we have recognized child partitions.

does no longer give partitioning systems precedence over file systems.
The one with the greater identification priority wins. ATM, if a file
system wins, we still mount the first file system that recognized the
partition at all, though.

indirectly, and since InsertText() is called inside
BTextView::HandleInputMethodChanged(), this method would see fInline
slip away from under its feet.. Now we call the BTextView version
explicitly. Fixes bug #1022, although I'm not sure if this is completely
correct.

* bfs_initialize():
- Report job progress.
- Rescan the partition after it has been initialized, so that all
partition_data fields are properly initialized.

* This is needed by everyone who calls this to make sure modifications to a
page aren't ignored. Namely, the page scanner and the page thief were
affected.
* Cleaned up locking the page's cache a bit in page_thief(); there is now
a helper class that takes care of everything.

* the page writer don't allow to block, while all other writers do. This fixes
bug #1509. The reason the page writer needs this is because it marks several
pages from different caches as busy.
* Fixed a warning about ASSERT being defined already in BFS, since
util/DoublyLinkedList.h now includes debug.h.
