* When writing a page failed it is not a good idea to re-enqueue it at the tail
of the modified queue, since that is definitely behind the page writer's
marker and the page would be picked up again before reaching the end of the
queue. If that happened with more than 256 pages, the page writer would keep
picking up only those non-writable pages and make no more progress.
* When selecting pages also skip temporary pages, if there's no more swap space
available, since trying to write those pages would most likely fail anyway
(triggering the first problem).

command terminates.

topmost iframe).

continuing before.

re-entered it fast enough, we wouldn't leave the loop and thus cause a
deadlock, since we wouldn't process the ICI message telling us to halt. We do
now call smp_intercpu_int_handler() in the loop and guard the function from
being re-entered. This also has the advantage that we can execute code on all
CPUs in the kernel debugger, if we have to.

enter/exit code. There's no real reason not to keep kernel breakpoints
enabled when in userland (unless there are breakpoints installed for the
team, of course).
* Enabled kernel breakpoints by default (check your kernel_debug_config.h,
if you have overridden it!), since they don't really add any overhead
anymore.

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

for a stack trace, if we haven't actually hit a symbol in the image. This
way we don't get "unknown" image hits for PLT slots anymore.
* In system profiling mode add the kernel images to new teams. The mode should
be usable now. Well, except maybe for the amount of data one gets.

image, but it refers to a SharedImage for the symbols, now. This allows us
to load the symbols for a shared object only once and share the data for all
teams referring to it.
* Made the area used for system profiling writable. "-a -f" would segfault
since the return addresses are sorted in-place.

Formerly two were implemented in ImageFile (from file, via syscalls) and one

ones.

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.

Jamfiles).
* Introduced build/jam/OptionalBuildFeatures which is supposed to do the setup
for optional build features that need it.
* Renamed USE_SSL to HAIKU_BUILD_FEATURE_SSL and made it more intelligent.
The OpenSSL optional package is downloaded and unzipped automatically when
enabled. Switching between enabled/disabled HAIKU_BUILD_FEATURE_SSL is
handled gracefully -- the concerned components are built in separate
subdirectories. Adding the OpenSSL optional package to the image also enables
HAIKU_BUILD_FEATURE_SSL.

page failed since the cache has been shrunk, we need not only remove the
page from the cache, we also need to remove all of its area mappings and
free it. Not removing the area mappings might have been the cause of #3110,
not freeing it would cause it to be leaked for good.
* vm_page_write_modified_page_range(): When writing failed for another reason
and the page wasn't in the modified queue before, we would lose the info
in which queue it was before and setting the page state to modified would
assume the active queue. This could potentially screw up our page queue
structures.

ntfs -- paths beyond the root directory could not be resolved.

* We started the "main2" thread too late. Since the scheduler was already
started on all CPUs, the idle thread could wait (for a mutex) while
spawing the "main2" thread. This violated the assumption in the scheduler
that all idle threads would always be ready or running. We now create the
thread while the kernel runs still single-threaded.
* scheduler_start() is now invoked with interrupts still disabled. We enable
them after the function returns. This prevents scheduler_reschedule() from
potentially being invoked before scheduler_start().

Don't really resume the undertaker thread after creating it, since at that
point the scheduler has not been started yet. Didn't do any harm, since it was

immediately.

KernelRequest which has respective attributes.
* Server: RequestThreadContext does now also save the request that is being
processed. Furthermore some space has been reserved for file system specific
data, which can be initialized by the new
FileSystem::InitRequestThreadContext().
* FUSE library: Implemented fuse_get_context() using the new
RequestThreadContext feature.

we need to enforce a global locking order on the node tree to avoid
deadlocks. Untested yet.

need to make sure that the paths of nodes don't change while we're meddling
with them. We read-lock the directories up to the root directory for that
purpose.
* Added missing locking for directory and attribute directory cookies.
We have to do that, since concurrent readdir()s on the same dir handle are
possible and we write-access the cookie data in such a case.

light-weight read-write lock, that doesn't use a semaphore itself. Locking
and unlocking has to be done via methods of RWLockManager. This combo allows
lots of locks without risking to hit the semaphore limit.

negative error codes now (e.g. using the new error mapping mechanism). This
is necessary since the read() and write() hooks have to return a size or a
negative error code.
* Implemented Read(). We can now read sshfs files.

ported software:
* If the macro B_USE_POSITIVE_POSIX_ERRORS is defined the POSIX error code
constants (ENOMEM, EINTR,...) will have positive values.
* Introduced the macros B_TO_{POSITIVE,NEGATIVE}_ERROR() which do convert a
given error code to a positive/negative value.
* Added static library libposix_error_mapper.a that overrides all POSIX
functions (save the ones I forgot to add :-)) directly meddling with error
codes (having them as parameter or returning them) dealing with the
positive<->negative error code conversions. The functions have hidden
visibility, so they affect only the shared object they are linked into.
* So ideally all one has to do is to build a ported software with
-DB_USE_POSITIVE_POSIX_ERRORS and -lposix_error_mapper and be good with
respect to error code problems.
* Potential issues:
- When mixing ported and Haiku native code, i.e. using Haiku native code in
a ported software or using a ported library in a Haiku native application
care must be taken to convert error codes where the two interface. That's
what the B_TO_{POSITIVE,NEGATIVE}_ERROR() macros are supposed to be used
for.
- A ported static library can obviously not be linked directly against
-lposix_error_mapper. The shared object linking a against the ported static
library has to do that. The previous point applies when that causes mixing
with Haiku native code.
- When dependent ported libraries are used probably all of them should use
the error mapping.
Comments welcome.

Listing the root directory with sshfs does now work. For subdirectories
stat()ing the entries seems to fail, which might be due to the yet missing

interface works with paths only, while our VFS plays with node IDs and
node cookies.
* Implemented most of the mandatory hooks (vnode operations, lookup, read stat,
open/close/read dir). I was hoping to get directory listings with sshfs now,
but as I had to find out, it implements the deprecated getdir() while we
only support the new {open,read,release}dir() interface yet.
