clearity as suggested by Philippe Houdoin once and brought to my attention by
Slavatore. As this definition is completely private to the USB stack it would
not have caused any conflicts though.

also free the device info which it must not do, as this info is in fact just
a pointer to the device info of the raw node. Removing a raw device that had
partitions published therefore always lead into KDL when closing the raw
device after unpublising the partition, as the close_hook pointer which sits
in the device info now was 0xdeadbeef. This should make for example unplugging
USB devices work as expected.

FIFO. Reimplemented pipe() to use it.
* pipefs is no longer mounted. Will remove the superfluous code soon.

inactive until at least one reader and one writer have opened it. As
long as it is inactive, reads from and writes to it just block. When
active, they behave as before (if there's no counterpart writes fail:
SIGPIPE + EPIPE, reads return 0). When both reader and writer count
drop to zero, the pipe becomes inactive again.
* Allocate the ring buffer lazily when the pipe becomes active and
delete it when it becomes inactive.
This makes the pipe implementation FIFO compatible. IOW, FIFOs work as
expected as far as I've tested them.

- Moved most file_system_module_info hooks into separate structures.
Those that operate on mounted volumes to fs_volume_ops, those
operating on a vnode to fs_vnode_ops.
- Got rid of the fs_volume, fs_cookie, fs_vnode typedefs. We use void*
again.
- Instead of a void* volume and node cookie hooks are passed a
fs_volume and fs_vnode structure pointer, which contain the cookie
and an ops pointer (fs_volume a few more things).
- The VFS {new,publish,get,...}_vnode() functions take a fs_volume*
instead of the volume ID. So does vfs_get_fs_node_from_path().
- Added type and flags arguments to publish_vnode() and the
get_vnode() hook and removed the type argument from lookup() hook.
Added vnode::type using formerly unused bits to store the node type.
Simplified a few things in the VFS due to the now always available
node type.
- Added fs_volume_ops::{create,delete}_sub_vnode() and
fs_vnode_ops::get_super_vnode() hooks. They are used to support file
system layers, e.g. allowing to extend an FS not supporting BeOS
attribute with attribute support. Needs some more work in the VFS.
- Added fs_vnode_ops::create_special_node() hook for creating special
nodes (e.g. FIFOs).
* Adjusted the built-in file systems and BFS according to the interface
changes. Removed all other FSs from the image for the time being.
We'll see whether further API changes are necessary before porting
them.
* Adjusted the bfs_shell accordingly.
* Implemented create_special_node() in rootfs to support special nodes.
* Added support for FIFOs:
- Added syscall _kern_create_fifo() (used by mkfifo()), which creates
a special node (type S_IFIFO) in the respective file system.
- When a special node is published the VFS creates a respective sub
node. Currently only FIFOs are supported.
- Added a little support for FIFO subnodes by using functionality from
the pipefs.
- Added mkfifo to the image. It can create FIFOs in the rootfs, but
the FIFOs aren't really usable ATM, since they still work like
pipes, i.e. readers and writers need to have them open at the same
time.
* Some smaller changes in the VFS:
- Made the *_CALL macros nicer to use (vargs).
- Refactored FS entry lookup into new function lookup_dir_entry().
- create_vnode() no longer just calls the FS create() hook. First it
looks up the entry and uses open_vnode(), if it already exists. This
is necessary for two reasons: 1) The FS might not support create()
while still allowing to open() entries. 2) When the FS has other
layers on to of it (or the respective node) it might not be
responsible for opening the node.

based one. The path based version could not have worked for entry removed
notifications at all as the node is removed from the directory at this point
already
* Forgot to delete the device watcher instance after removing all monitors
* The PartitionRegistrar in DeleteDevice() was set to already locked which is
not the case
* Someone probably forgot to add a PartitionRegistrar to the media checker - it
did register the device on each run but never actually unregistered it, which
obviously messed up the reference counting a bit

Haiku. Support for undefined symbols is nice in principle, but not
really needed for building Haiku itself, and can get little annoying, if
one really just forgot to link in a symbol or has a typo in a function
name in C code.

and ino_t instead of a path. Supposed to work with node monitoring messages.
Took the name from vfs_entry_ref_to_path() that takes the same arguments, but
suggestions for a better name are welcome.

* Implemented RLE compression for the boot splash images, resulting in
smaller kernel and boot loader.
* Only the boot loader contains the RLE compressed images, the decompressed
buffer for the icons is passed to the kernel via kernel args.

* Also updating device->open_count must be protected by the device list lock
This fixes the (unlikely) case where a device was removed from usb_disk
standpoint while it still had an open read/write/ioctl operation.

if the volume is read-only. This should help with #2028.
* Removed unused bfs_[de]select() functions.
* Removed most paranoia checks - now that we control both sides of code,
this would just hide eventual problems in the VFS code.
* Cleanup.

directly. This should fix#2008 again.

MMU code reserves for the kernel, and we hit that limit recently with the
addition of the boot splash code.
* This fixes the boot crash as triggered by Stippi's recent changes to the
splash image.
* Cleanup (doxygen comments, line length).

that do not support it (probably because they do not have a cache at all like
in flash media) and this should at least avoid spamming the syslog when this is
the case. It will try 5 times and then disable syncing for that device. Untested
as of yet though.

* A device now has one or more LUNs which are used for LUN specific functions
* Adapted these LUN specific functions to the new design and also change the
(un-)publishing accordingly
* Handle "no media" cases more correctly
* Output some interesting device infos also with tracing disabled
* Add some more helpful debug output here and there
Devices that provide multiple logical units (like those n in 1 card readers)
should now be usable with usb_disk too. Also we don't fail when a device is
attached which currently does not contain a media. Instead handle media changes
correctly so inserting a media works as expected. Note that hot-unplugging and
media removal still does not quite work right at the devfs or disk device
manager level and easily crashes the system.

The dividing line is back although with a little more spacing. Also the icon
spacing is a little increased and I added a subtle outline as well as a little
brighter background for the active icon look. The placement logic is now not
independant of each other anymore, otherwise I couldn't center both images
as a unit. But only the vertical placement is affected.
Comments as always on the commit mailing list... :-)

volumes with a broken log. It will only allow the volume read-only then,
though (unlike Be's BFS), as your disk could be corrupt.
* Added InitCheck() method to the RecursiveLock class, and now only check
this one in Journal::InitCheck() instead of also replaying the log there;
this is now done directly in Volume::Mount().

and setting the video mode. The result of this is a garbage display every other boot. By
introducing a small wait before doing the mode set, it works every time. Will see if I can
reduce the spin timer though with some more tests.

space left for the new log entry, it did call cache_sync_transaction(), and
then just assumed the space would be ready. But since the transaction could
have been written before that call by the block writer, and since the
_TransactionWritten() hook is now called asynchronously,
cache_sync_transaction() actually has to flush all pending TRANSACTION_WRITTEN
notifications before returning to the caller.
* To implement this, block_cache now publishs a condition variable, and
wait_for_notifications() adds a fake notification that signals that one.
Since the notifications are handled in FIFO order, this guarantees that
the previous TRANSACTION_WRITTEN hook is done.
* notify_transaction_listeners() could accidently delete notifications that
still had pending signals. Now, it will defer the deletion to the notification
thread instead in that case. This should fix bug #2008.

wrote the super block, so there was a race condition with what
_WriteTransactionToLog() assumed was already written there (if it managed to
write the log entry before the super block was written by
_TransactionWritten(), and a reboot happened just then, the log start could
point to an invalid log entry). Not very likely, but it could happen.

Haiku code, they work around buggy BeOS code not present on Haiku.
* If this code turns out to be problematic under Haiku (Bruno, did your changes
make any difference at all?), then please fix the problems in the Storage
Kit, don't enable work-arounds for BeOS.
* Simplified the macro check as suggested by Ingo.

during the build process. Added checking for HAIKU_HOST_PLATFORM_HAIKU where
relevant.
