the value, otherwise it would not work correctly in some tricky conditions,
inserting unnecessary undo steps or none at all for example when changing a
value, applying and then changing it back manually and switching focus.

in VMCache, but, if anything, that makes a -j8 build marginally slower. I
guess busy vnodes are encountered so rarely that the additional overhead for
a more intelligent algorithm isn't really worth it. Reduced the wait time,
though.

stores the value right-shifted by 12 bits, now, since those bits are not
relevant. This saves some bits and also resolves a TODO.

destruction and VMVnodeCache::AcquireUnreferencedStoreRef(). Solved by
adding a flag to VMVnodeCache and letting AcquireUnreferencedStoreRef()
fail, if set.

error.

* When interrupts are disabled, it is still safe to capture the kernel stack
trace. The respective TODO preceded the introduction of the "kernelOnly"
flag.
* Actually made "kernelOnly" work. The wrong flag was passed to
arch_debug_get_stack_trace() in case it was false, so we never captured
user stack traces.

directory iteration code, a mutex to protect the iteration cookie and one
to protect the cookie list have been introduced.
Overall this reduces the contention of the rootfs lock significantly. The
Haiku image -j8 build gets only marginally faster though.

* Changed the rw_lock_{read,write}_unlock() return values to void. They
returned a value != B_OK only in case of user error and no-one checked them
anyway.
* Optimized rw_lock_read_[un]lock(). They are inline now and as long as
there's no contending write locker, they will only perform an atomic_add().
* Changed the semantics of nested locking after acquiring a write lock: Read
and write locks are counted separately, so read locks no longer implicitly
become write locks. This does e.g. make degrading a write lock to a read
lock by way of read_lock + write_unlock (as used in the VM) actually work.
These changes speed up the -j8 Haiku image build on my machine by a few
percent, but more interestingly they reduce the total kernel time by 25 %.
Apparently we get more contention on other locks, now.

values are not really useful, since they should only be != B_OK in case of
user error, and will be changed to void.
* Added tests for write lock to read lock degrading.

a driver which publishes a device as "/dev/kernel_unit_tests". Commands
can be issued by writing to the device (e.g.
"echo help > /dev/kernel_unit_tests"), output is written to serial port/

the function shall nevertheless return the length of the string that would
be written, if the buffer were large enough.
Added a touch of C++ while doing that. :-)
* Fixed the instances in boot loader, kernel, and kernel modules where the
wrong semantics were expected. The majority of uses actually.

on wlan stack shutdown, now.
* Added patch by mmlr to support IBSS (aka Ad-hoc) mode. To activate IBSS mode
one would need recompile the wlan stack, though, once the constant in
start_wlan() is switched from IEEE80211_M_STA to IEEE80211_M_IBSS. There is
no runtime configuration, yet.

wlan drivers.
