allows event listeners to add new listeners inside a node monitoring event
(i.e. if one wants to add a listener for the entry that has just been created
and triggered the current notification).

Instead return the directory vnode, so the calling function can insert it after
all vnode initialization is done. Otherwise entry created notifications are
sent upon inserting the node into the directory for vnodes that are not yet
fully initialized (i.e. they have no type or the device hooks are not yet set).
That would cause for example ioctls to fail when someone would react to a
notification of a newly created device.

block_writer() as well as notify_transaction_listeners() must update their

overcommitting stores:
- has_precommitted was incorrectly set to true in the constructor
- when a precommitted page was committed, vm_store::committed_size
was still changed.
- unreserving memory did not update vm_store::committed_size.
- when precommitted pages were committed, their page count instead of their
size was reserved.
* All this lead to bug #1970 which should be fixed now.
* Cleanup of vm_cache.cpp, no functional change.

* Replaced the block_cache::lock benaphore with a recursive lock, so that
you can call cache functions from within the notification listeners.

r24721/r24722. After resolving a symlink we weren't updating the local
type variable to the type of the link target, so that the directory
check in the next iteration would always fail.
* Added TODO.

* Now also checks if the first part of the path is a directory.

first loop - the vnode passed in would still need to be checked, though.
Eventually, it would be nice to move the check to the top, though, so that
we don't need to search for the patch delimiter twice.

as expected by POSIX programs. This allowed be to compile Haiku under itself
without any hacks at all, so I guess this means that now we are officially
self-hosting!

in the buffer, they need to be notified after a read when their
minimal write size requirement has just become satisfied. We were
notifying only when there was no space in the buffer before, which
caused bug #1755.
* Removed Inode::NotifyWriteDone(). It's not needed anymore, since we
don't queue writers. They are always all notified, so that one doesn't
have to notify the next one, when it's done.
* Renamed *Request* to *ReadRequest, since we do have WriteRequests now
as well.

item entry.
* The bios_ia32 video platform code now stores the available VESA modes in
the new vesa_modes kernel_args field.
* When configuring a VESA mode via settings file, it's no longer needed to
specify the exact mode - the closest available mode is now used. This should
help with bug #1962.
* frame_buffer_console_init() now also creates a boot_item for the VESA modes
in the kernel_args.
* The VESA accelerant now filters the mode list to only contain modes that
are actually supported.
* Moved non-shared vesa driver data into its own file vesa_private.h.

- Added a "root" vnode to the io_context. It is used for resolving
paths and converting nodes to paths instead of sRoot. Some more
passing around of io_context structures was necessary.
- Introduced a new lock sIOContextRootLock to protect
io_context::root. The current uses of io_context::io_mutex
(put_vnode(), remove_vnode() while holding it) looked too suspicious
to use that mutex in vnode_path_to_vnode().
- Added _kern_change_root() syscall and chroot() libroot function.
- Added chroot coreutils program to the image. Funnily it seems to be
much easier to set up a little jail than under Linux (just copy
bash and libroot.so into respective subdirs; mount another pipefs
if you want pipe support).
With Haiku allowing direct access to directories via inode IDs
jailing is obviously not very secure at the moment.
- Added /var/empty to the image. It will be the chroot target for ssh.
* Changed vfs.cpp:get_cwd() so that the io_context::io_mutex is no
longer held when calling dir_vnode_to_path().

- The kernel stores the group IDs in the team structure. They are
correctly inherited on fork() and load_image_etc().
- Implemented getgroups() for real, i.e. it retrieves the groups
associated with the process.
- Implemented setgroups(), initgroups() and (the BSDish)
getgrouplist(). The latter two read the group information from the
"group database" /etc/group (if existing).
- Change the BIND port config, since we do have getgrouplist() now.
* The set-uid feature was broken when the path to the executable was
relative, since we used stat(), which, in the kernel, uses the kernel
IO context.

* Shuffled functions around to separate the private from the public API.
* Renamed global static io_vectors to sVectors.
* Rearranged includes, replaced deprecated malloc.h with stdlib.h.

finally created a solution to avoid that: Header files that contain
configuration settings (and nothing else) go to build/config_headers.
To change settings, create a directory build/user_config_headers (which
is ignored by svn), copy the respective header there and modify it at
your leisure. Currently only tracing_config.h has been moved to the new
location, but more files will follow eventually. It is also recommended
to move optional macro definitions in Jamfile (as for BFS) to a config
header instead; the build system will then automatically rebuild on
changes.

vnode from the hash before putting it caused all sorts of problems.
* For example, BFS would trim its preallocations when the vnode is put;
if someone would read that same vnode after it had been removed, but
before BFS could trim it, it would read the old vnode which still
seemed to own the blocks which would subsequently be freed.
* This fixes bug #1914, and should also fix bug #1956.

not referenced and clean (is no longer part of a transaction).
This finally gets memory consumption to a moderate level; even
unpacking a large archive will no longer eat all memory.
* The "block_cache" KDL command will now print the number of unused
blocks as well.

* Added a new KDL command "calling" that you can use to get a list of
threads that have a specific function in their call chain.
* Removed extraneous white space.

* It now also uses parse_expression() for its second argument, since it
now returns an uint64 in Haiku.
* Tracing output cut off the label too early.
* Minor cleanup.

* Add a cached_pages field to the system_info structure, and change the
meaning of the used_pages field to not include cached pages.
* Provide the needed info using the new calls vm_get_available_memory(),
and vm_page_num_available_pages().

file system to not fill newly created space with zeros.
BFile::SetSize() now uses this, while [f]truncate() does not. This
is only a temporary work-around until BFS supports sparse files.
* Apps that want to reserve space to fill up later should use
BFile::SetSize() for now, as this will be a lot faster than
[f]truncate().
* cache_io() and the functions below now use a special mode when you
pass in a NULL buffer: for read access, the cache is only populated
(useful for prefetching), for write access, the file is filled with
zeros.
* Implemented BFS's Inode::FillGapWithZeros() using this method now.
* Removed extraneous white space.

* Removed extraneous white space.
* net_server settings are now also updated when the size of the
file changed.

time. Releasing the cache's store reference while holding the cache lock
could reverse the usual locking order -- the VFS could potentially call
the remove_vnode() or put_vnode() FS hook, which in turn could use the
file cache, thus resulting in a deadlock. Now we release the store ref
before locking the cache.
