eventually the VIP heap would be exhausted.
* WriteAsync() didn't call the provided callback when an error occurred
before invoking vfs_asynchronous_write_pages(). The page writer would
get stuck in those cases.
* The object cache used for the swap blocks does now use the
asynchronous resizing feature to avoid deadlocks.

of free objects an object cache should try to have ready. If the number
of free objects drops below the threshold, a new urgent priority thread
is asked to asynchronously resize the object cache (pretty similar to
the heap grower thread). Such a mechanism is necessary for code paths
that are supposed to free pages, but may need memory themselves (like
the swap support).

calls the method unchecked, and the buffer can actually be NULL, if
Init() failed.
* panic() when running out of VIP memory, at least when KDEBUG is
set.
* Use heap_set_get_caller() for the VIP heap, so the heap leak checking
produces useful caller addresses.

is enabled to set a per-heap get_caller() function.
* Added "-h <heap>" option to the "allocations_per_caller" command. If
given only the allocation for the specified heap are considered.

- Includes all relevant handling of CDDA exported attributes so you guys can
see where I am going with this.
CDDB handling (including server connection, request and response parsing)
will come up next. In the future we will also have a configuration panel
and a Deskbar replicant for controlling it.
Do we really have to edit the Jamfile in the parent dir to get something
building with our build system?

Ctrl or Alt mode. Appearance needs a serious style cleanup, comming next
:)

we must use {read|write}_pages() instead of {read|write}().
* This should fix accessing other file systems than BFS (ie. those that doesn't
have an io() function) like ext3 and FAT.

Unless we implement a more flexible solution, we can't really customize
these
keys in the keymap anyway (for ex: Menu preflet will wrongly detect
the mode, and if you change it, it will overwrite your keymap with the
default hardcoded values anyway)

The recognition code is actually working, I was just using the wrong dvd. I'm now
using an iso file created with mkisofs.

* uncommented udf_recognized function call in Mount method
* minor clean up

attribute name as input. Handy for whyen we do not have an Attribute object
around.
- Made the non-static version fall back to the static version.
- Also check for the protected namespace when creating attributes. For
consistency, we should also not be able to create attributes in this
namespace.
- Added some new style violations. ;)

- All CD:* attributes can not be directly edited by the user as they are
internally maintened by the add-on itself.
- Style updates (thanks Stefano!)

cddblinkd) to know if they should lookup the CD or not. It will be true
unless:
1 - The CD has CD-Text information.
2 - The user (or a userland program) changed the Volume name.
3 - The user (or a userland program) changed any track names.
- Moved (again) attribute creation to before the stored attributes are read. As
attribute operations happen in memory in cdda, we don't need to care about
the IO cost and this way it is more in line with all the other attributes
created.

* Better formatting code
No functional changes.
Right now the code fails on recognizing the descriptor sequence.
I have to figure out if I pass the wrong values to the function.

global cache list before locking it. This allows to get rid of the
block_cache::deleting field, as well as simplifies some code.
* This also fixes a possible deadlock I recently introduced (on destruction,
the locking order was wrong).
* Now uses an anonymous condition variable instead.
* Moved the block_cache initialization code into a dedicated method that will
now also fail in case the low resource handler couldn't be registered (as
pointed out by Salvatore).

This does not change anything but makes more sense anyway.

* Fixed lock leak in Write().
* Fixed bug in _Commit(): swap_space_reserve() was fed with the wrong
value (could even be negative).
* swap_free_page_swap_space(): Removed incrementing of sAvailSwapSpace.
The function is only supposed to deallocate swap space, not to
unreserve it.

operation is available ATM, it will return NULL.
* _Finisher() does now re-schedule a request, if all of its operations
finished successfully, but there are still remaining bytes.
* _Scheduler() does now operate in two passes. First it creates as many
operations for a given request as possible, then it executes the
operations. This fixes bug #2644. The problem was that by creating and
executing the operations in a single loop, an operation could be
finished before the next one was added. The request would thus be
considered finished and the request owner be notified. This would
usually lead to the destruction of the request while it was still in
use.
* _Scheduler(): In case we don't have a DMA resource also advance the
request.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27070 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Moved memory unlocking from IORequest::OperationFinished() to
IORequest::NotifyFinished(). This way we can reschedule a request,
e.g. if we didn't have enough unused IOOperations at hand the first
time.
* Added some more debug output and asserts.

* Enlarged the serial buffer that is handed over to the kernel to 8192 bytes.
* Minor cleanup.

node it is requested to open. That this would happen was an assumption of
the FileTypes preflet. Adding an icon to a node from the FileTypes add-on
will now work. Previously, Icon-O-Matic thought this was supposed to be an
icon file. Perhaps it would be better if Icon-O-Matic would ask the user if
adding an icon was the intention. FileTypes could put a flag into the message
to supress this alert. On the other hand, if adding an icon was not the
intention, the user may as well simply close Icon-O-Matic.

* Some renaming: A location in a swap file where a page can be stored is
now called "slot" instead of "page" or "swap page".
* swap_slot_alloc(): Update the hint more correctly after allocating
slots at the hint.
* swap_space_reserve(): When less than the requested space could be
reserved, it always returned 0 and leaked the remaining pages.
* swap_file_delete(): sSwapFileListLock wasn't unlocked in error cases.
Use MutexLocker now.
* swap_free_page_swap_space(): sAvailSwapSpace wasn't updated.

be passed on to the IORequest. Most relevantly physical pages can now
be written directly by passing B_PHYSICAL_IO_REQUEST.
* Added VMCache::WriteAsync() which is supposed to write pages
asynchronously. The base class version version falls back to the
synchronous Write(). Only VMVnodeCache implements WriteAsync() ATM,
VMAnonymousCache (swap support) still has to be adjusted accordingly.
* write_page() doesn't need to map the page anymore as it can write the
physical page directly.
* Modified the page writer to write pages asynchronously. This shouldn't
have any noticeable effect yet. It will though as soon as the I/O
scheduler reorders I/O operations.

AsyncIOCallback is used to inform the caller when the request has been
finished.

* Added IORequest::Create() for creating a IORequest on the heap
(respectively the VIP heap).
