with vm_cache_acquire_locked_page_cache().
* Added new function vm_page_num_unused_pages() which returns the pages that are
actually completely free and unused.

C friendly it's not an actual base class, but casting to it is fine.

* Implemented a way to do asynchronous pre-fetching when mapping files.
* There are slight code duplications in some places that could benefit
from cleaning up, but nothing too bad.
* Implementing smarter ways to trigger prefetching and more analysis of
the situations in the kernel would be nice. Currently up to 10 MB
of every mapped file are pre-fetched without further analysis.
* The speed improvement is nice for certain operations. On our test
system (real hardware), Firefox took 9 seconds from being launched
to display a window. Now it takes 5 seconds. Both measurements
right after booting. The same system took 35 seconds from launching
Haiku in the GRUB menu to displaying the Tracker desktop background
image. Now it takes 27 seconds.
* We didn't have the chance to check out the effects of this on the
CD boot, but potentially, they could speed it up a lot.

more work concerning navigation within BTextView:
* pressing HOME on last line works again
* made public versions of LineAt() do what is required to pass back the
correct value even for the last line of the buffer (original implementation
has been moved to private _LineAt())
* PAGE_UP/PAGE_DOWN now moves the view by the bounds-height, making the
behaviour somewhat less confusing (IMHO, please shout if that's not
acceptable for you)

socket could be acquired, ie. when its reference count is 0, it cannot be
acquired anymore. This requires the protocol to do proper locking, though.
* The TCP EndpointManager now checks the return value of acquire_socket(), and
only returns the endpoint if that succeeded.
* This fixes bug #2197.
* Minor cleanup.

- Some styling

- Moved scheduler listening interface to <listeners.h> and added more
convenient to use templatized notification functions.
- Added a listener mechanism for the wait objects (semaphores, condition
variables, mutex, rw_lock).
* system profiler:
- Hopefully fixed locking issues related to notifying the profiler thread
for good. We still had an inconsistent locking order, since the scheduler
notification callbacks are invoked with the thread lock held and have to
acquire the object lock then, while the other callbacks acquired the object
lock first and as a side effect of ConditionVariable::NotifyOne() acquired
the thread lock. Now we make sure the object lock is the innermost lock.
- Track the number of dropped events due to a full buffer.
_user_system_profiler_next_buffer() returns this count now.
- When scheduling profiling events are requested also listen to wait objects
and generate the respective profiling events. We send those events lazily
and cache the infos to avoid resending an event for the same wait object.
- When starting profiling we do now generate "thread scheduled" events for
the already running threads.
- _user_system_profiler_start(): Check whether the parameters pointer is a
userland address at all.
- The system_profiler_team_added event does now also contain the team's name.
* Added a sem_get_name_unsafe() returning a semaphore's name. It is "unsafe",
since the caller has to ensure that the semaphore exists and continues to
exist as long as the returned name is used.
* Adjusted the "profile" and "scheduling_recorder" according to the system
profiling changes. The latter prints the number of dropped events, now.

being. Obviously we'll have to think of something different when we support
speed-stepping on models with frequency-dependent TSCs.

written by using the new CanWritePage().

* strlcpy() isn't a particularly good string compare function.
* BDebugEventInputStream::_GetData():
- Also need to reset fBufferPosition to 0 when the buffer is empty.
- Fixed read position.
BDebugEventInputStream does now actually read the files written by
BDebugEventOutputStream.

* Ensure that the device selection bit is set correctly for all commands.
* Generally disable interrupts and enable them only when expecting a DMA one.
* Renamed disk failure to device fault according to specs.

passed in a structure now, so it is easier to extend it and ignore unused
parameters.
* One can now select which system profiling events one is interested in.
* Added scheduling events to the system profiling interface. Those are pretty
much the ones recorded when scheduler tracing is enabled. Still missing are
the "wait object" events that allow to interpret what a thread is waiting
for.

input_server filter if the screen saver should be run could be confused if
additional option flags were turned on. I've removed the SAVER_DISABLED
definition completely. Also, I renamed the confusing "fEnabled" member, which
really means "saver already running".

system profiling mode is asynchronous, so the team or thread in question
could already be gone.

ones.

methods that used an "event mask" field. There was no need to introduce
a "flags" field for the same purpose.
* Renamed protected DefaultNotificationService methods (removed "_" prefix).
* Adjusted the code providing a notification service accordingly.
* Changed the event message several notification services generated by renaming
the "opcode" field to "event".
* Implemented the TEAM_ADDED event and also added a TEAM_EXEC event.
* Added notifications for threads and images.
* Added visitor-like iteration functions for teams, threads, and images.
