* read_dir() is supposed to return B_OK and and a count of 0 when
reaching the end of the directory. In case the node in question could
not be found, we were looping infinitely.
* free_dir_cookie() was not invoked.

* Removed superfluous memset() of select_sync structures.
* Some cleanup.

short, if the FD table size wasn't a multiple of 8.
* vfs_resize_fd_table() didn't seem to know at all about the
close-on-exit bitmap. The pointer in the io_context would point to
free()d memory afterwards. This explains the sporadically closed
stdin/out/err descriptors in programs started from Tracker and
Deskbar.

add-ons accordingly and removed the syscall.
* Removed send_notification().
* Reimplemented notify_listener(). It used the unimplemented
send_notification(). Now it has a chance to work. Note that
notify_listener() is obsolete. I would already have removed it, if
there weren't lots of FS implementations still using it (Hint!).

vnode::covered_by fields. Together with sMountOpLock it allows write
access, either lock alone suffices for read access. Before
sMountOpLock had to be acquired for read (and write) access, which
meant that while mounting/unmounting a FS path resolution would have
to wait. In case of the UserlandFS this would even cause a deadlock
while mounting if the client tried to resolve the path of the device
to be mounted (e.g. by opening it).
* Added a clarifying comment about read access to the
fs_mount::covers_vnode/root_vnode field and removed locking in
resolve_volume_root_to_mount_point() which was not necessary for
explained reasons.

name (saves copying the name, if that has to be done anyway) and added a
wrapper version with the old interface.
* dir_vnode_to_path() was broken for file systems that didn't support
the get_vnode_name() hook. It resolved the mount point too early, so
that it was searching the mount point and not the FS root dir for the
node. It uses the get_vnode_name() function now (before resolving the
mount point).

This fixes a possible crashing bug when an application with disconnected descriptors
quits.

will now grab a reference to the vnode as well if successful. This way, vfs_get_vnode_cache()
now actually works how it should: it will now always grab a reference to the cache and
its underlying vnode. This removes an extra reference to the vnode (and vm_cache) that
got ignored before and prevented volumes to be unmounted (or file caches to be removed).
Thanks to Korli for pointing this out.
* file_cache_create() is now aware of that extra vnode reference and releases it; unmounting
volumes is now working again as it should.

* Moved devfs_get_partition_info() into the devfs_ioctl() hook.

wouldn't be that clear to the user).

scan job in the calling thread).
* KDiskDeviceManager::InitialDeviceScan() now runs synchronously, so that
get_boot_partitions() doesn't need to do this ugly wait hack.
* KDiskDeviceManager::CreateFileDevice() can now run synchronously as well, which
fixes a deadlock in fs_mount() - note, mounting file devices still doesn't work,
though as Haiku's BFS doesn't allow this right now.

dir_remove() did not normalize the path, and thus, could forward a "." as
name for the removed directory - which BFS didn't catch because it assumed
our VFS would work correctly...

vnode is not becoming unbusy (right now it even panics, but that can be removed
later on).

* vfs_get_fs_node_from_path() now also work for absolute paths again (but
still for relative ones from the volume root) - it just tests if the
mount IDs fit, so it only returns successful if the path really is on
the desired mount.
* the Disk Device Manager publish functions now call devfs_publish_*()
correctly (by omitting the "/dev/" mount point).
* devfs_publish_partition() now accepts absolute device paths but relative
partition paths.

all).

systems a chance to know if they have locked already.
This fixes a locking problem in BFS where one thread tried to acquire two read
locks (where someone else trying to acquire a write lock would have caused a
dead lock).

changes made to a file instead of directly using vm_cache_write_modified() -
besides making the file system more independent from the file cache, this also
works around a possible dead lock (that is to be fixed in a later commit).
* fs_sync() no longer uses vnodes from the mount's vnode list directly to write
back the changes made to them, but gets them via ID instead - this makes sure
the vnode is in a valid state and fixes a race condition with free_vnode().

with bug #357.

* devfs_unpublish_device() can now optionally make use of this call.
* Fixed the type check of devfs' unpublish_node().
