Patch by Mika Lindqvist. Could we give give him Commit access?
I am getting daily patches from him with fixes and new features.

the thread issuing the command called acquire_sem_etc() on the semaphore
that the interrupt handler would otherwise release. The semaphore is now
released unconditionally, but to prevent the race condition that the
B_RELEASE_IF_WAITING_ONLY was trying to avoid, it is released with the
spinlock held.
* The error interrupt handler did not reset the fCommandsActive flag, but
it seemed to us like it should do that.
* WaitForTransfer now also acquires the spinlock to reset fCommandsActive,
which may be unnecessary but does not harm either.
* Cleanup of some long lines, sorry for mixing that with the actual fix.
Fixes bug #2359 (long pauses when accessing the disk).

* Turn off text cursor when switching to text mode.
* Minor cleanup.

them with the ROUNDUP macro that was specifically made for this task so that
too tired developers do not mess up the calculations...
* Don't use area allocation during kernel startup (not that it really happened).
* Minor simplification of similar calculations in heap_attach().

contiguous pages, it will request growing even if there are still more than
10% free pages available. Previously that case was not handled anymore and the
allocation would have just failed. Note that this is a pretty rare case, as
there are no "large" allocations happening in either the small or large heap
classes, but only in the huge one for allocations between 128KB and 1MB.

does in fact happen, as there are objects used in the kernel that allocate
with new, which in turn uses the heap. The OpenHashTable used from the slab
allocator hit this case during an svn checkout here, because it grows it's new
allocated list by doubling the list size. Added some unconditional debug
output for those cases to monitor the usage for now. All of that not yet really
tested though.

that looks like a compiler bug to me, though.
* Pulled struct data_stream out of the union (now called ext2_data_stream),
based on a patch by Maurice, thanks!

ext2_super_block::first_data_block must be used; the superblock offset
doesn't matter if the block size is greater than 2KB.
* Fixed block access beyond the 4GB limit - we need to cast the block to
a 64 bit type in ext2_get_file_map() before shifting it.
* Tested with various larger ext3 disks, and everything seems to work fine.
* Added some optional debug output.
* Minor cleanup.

(it didn't really work previously anyway). The only alignment really used seems
to be B_PAGE_SIZE, which happened to always work out before, because anything
larger would have been allocated using individual pages anyway. Since larger
bins are now available and with kernel heap leak checking enabled an allocation
of B_PAGE_SIZE with B_PAGE_SIZE alignment is actually a bit bigger than
B_PAGE_SIZE, it got into the 5KB bin, which didn't guarantee the alignment
anymore. This would have caused a tripple fault on boot when kernel heap leak
checking was enabled. The alignment is now taken into account when picking
the bin for the allocation. Added a more detailed TODO as to why this isn't
the best thing (wastes space) and how it could be changed if deemed necessary.

Implemented the needed fs API hooks to support identifying partitions
(so ReiserFS partitions appear in the Tracker Mount menu now).

serve, bin sizes and page size. This minimizes the amount of "large"
allocations made in heaps that don't have a bin for the allocation size
(combining multiple pages). This is desirable as such large allocations
are generally pretty inefficient, and also because it separates larger from
smaller allocations better, making the chance of a heap becoming empty higher.
For now there are three heap classes "small", "large" and "huge", with a
predefined set of bin sizes for each. This might need some finetuning later on.
Reduce the grow size to 4MB though as the allocations should now be spread
across heap classes which each grow on their own.

allows for dynamic (heap)page sizes. It's currently just set to B_PAGE_SIZE
but I'm expermienting with the creation of differently sized heaps that could
use dynamic page sizes with that.

Report the index where the event opcode pair has been found.
Currently server was expecting them to be the first entry of the request

the cancel, it wasn't actually done. This could bring a device out of sync in
the case timeouts actually happened (which shouldn't be a commen case).
Fixed that and increased the timeout to 2 seconds in favor of slower devices.
Might need some fine tuning later still.

Avoid unhandled event in the bluetooth_server
by Mika Lindqvist

Fixed race conditions when a ServerApp or ServerWindow is created. The
reply to the client that the object has been created successfully was
sent in the thread creating it. Preempted at the wrong time (right after
writing the message to the port) could lead to the object's thread using
the link at the same time, which would screw up all subsequent
communication via that link.
This fixes the problem that mimeset would sometimes fail when building
Haiku in Haiku (can't find the ticket). It probably also fixes#2331,
and the bug that sometimes when a window is opened (Terminal, crash
alert, shutdown window, etc.) it would come up with huge width/height
and tiny other dimension (can't find the ticket).

* It's not yet complete, doesn't support some ext2 stuff (like files over 4 GB),
and might have some other bugs (I only tested it with a single 20 MB ext2
image).
* To have a read/write ext2 file system, it would probably make more sense to
port GNU sources (like ext2fs lib), and use that. But a small read-only ext2
file sytem doesn't hurt, I think, and I don't know if ext2fs lib would be
feasible for kernel use (porting the file system from Linux directly would
also be an alternative, but probably more work).
