1da9f5cea5 * Added BDiskSystem::ShortName() and everything needed to get it there.
* Added BDiskDeviceRoster::GetDiskSystem() method, that can get a disk system
  by short/pretty/module name - since they should all be unique, I put them
  in a single namespace, please complain if you don't like that :-)
* Cleaned up DiskSystem.h and DiskDeviceRoster.h according to the updated
  header guidelines.
* Renamed ntfs pretty name from "ntfs File System" to "Windows NT File System".

7ffafac8d7 * Reorganized the FS interface a little:
- 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.

a121b8c83c * Added a new flag for write stat: B_STAT_SIZE_INSECURE that allows a
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.

5e2ef462ec * Got rid of the duality of FS_WRITE_STAT_* vs. B_STAT_* flags (removed
the former ones).
* Removed extraneous white space.
* net_server settings are now also updated when the size of the 
  file changed.

3d268eda3d * Extracted file_map API out of the file cache - it's now an optional service
that can be used by file systems.
* Changed the way the file cache works: instead of reading/writing to the
  underlying device directly, it can now be used for any data source, ie.
  also network file systems.
* As a result, the former pages_io() moved to the VFS layer, and can now be
  called by a file system via {read|write}_file_io_vec_pages() (naming
  suggestions are always welcomed :-)). It now gets an FD, and uses that to
  communicate with the device (via its fs_{read|write}_pages() hooks).
* The file_cache_{read|write}() functions must now be called without holding
  an I/O relevant file system lock. That allows the file cache to prepare the
  pages without colliding with the page writer, IOW the "mayBlock" flag can
  go into the attic again (yay!).
* This also results in a much better performance when the system does I/O and
  is low on memory, as the page writer can now finally write back some pages,
  and that even without maxing out the CPU :)
* The API changes put slightly more burden on the fs_{read|write}_pages()
  hooks, but in combination with the file_map it's still pretty straight
  forward. It just will have to dispatch the call to the underlying device
  directly, usually it will just call its fs_{read|write}_pages() hooks
  via the above mentioned calls.
* Ported BFS and FAT to the new API, the latter has not been tested, though.
* Also ported the API changes to the fs_shell. I also completely removed its
  file cache level page handling - the downside is that device access is no
  longer cached (ie. depends on the host OS now), the upside is that the code
  is greatly simplified.

bf95c9aee6 * The shadow_changed() FS and partitioning system hooks take an
additional partition_data* child parameter now.
* _user_get_partitionable_spaces() doesn't need to copy the buffer into
  the kernel, since it is no input parameter. It also copies back the
  actual partitionable spaces count on error, now -- B_BUFFER_OVERFLOW
  is returned when the buffer was too small, but then the count must be
  returned too.
* Fixed several instances of syscall implementations that unloaded a disk
  system, although they didn't load it in the first place. This screwed
  up the load count with undesirable consequences.
* _user_create_child_partition() would set the size to the supplied
  offset.
* Fixed broken loop in KPhysicalPartition::CreateShadowPartition().
* KPartition::RemoveChild() notified the listeners about the wrong
  event.
* Intel partitioning module:
  - The *_get_partitionable_spaces() correctly return B_BUFFER_OVERFLOW
    now, if the supplied buffer is too small.
  - Implemented a part of pm_shadow_changed(), which creates and updates
    the PartitionMap, so that the validate_*() hooks have a chance to
    work at all.

db5c68ca46 * Added the partition size as parameter to the file and partitioning
system initialize() hooks. It's often the only info about the
  partition one needs and thus locking the partition just to get it is
  no longer necessary.
* intel partitioning system:
  - Removed passing around block sizes. We require 512 byte sectors
    anyway. In fact using the parent partition's block size was even
    wrong.
  - Simplified writing the partition map sector.
  - Simplified and corrected the partition map initialization.
  - We don't fail identifying a partition anymore, if the partition map
    contains no partitions. We would never identify a freshly
    initialized partition map before.
  - Made pm_identify() more intelligent: It determines the priority to
    return depending on whether the partition is the device itself and
    whether we have recognized child partitions.

3e9513aa4a * fs_{write|read}_pages() now has an additional argument "mayBlock".
* the page writer don't allow to block, while all other writers do. This fixes
  bug #1509. The reason the page writer needs this is because it marks several
  pages from different caches as busy.
* Fixed a warning about ASSERT being defined already in BFS, since
  util/DoublyLinkedList.h now includes debug.h.

76a8ec23db * Added disk system flags for whether a partition name and partition
content name are supported.
* Added file_system_module_info::flags (analogously to
  partition_module_info::flags) which indicate which disk device
  features the FS supports.
* Replaced the
  file_system_module_info/partition_module_info::supports_*()
  hooks by a get_supported_operations() hook and for partitioning
  systems additionally a get_supported_child_operations() hook.
* Updated file and partitioning systems accordingly.
* Updated fs_shell accordingly.
* Updated the DDM accordingly. The syscall interface remains unchanged,
  though.
* _user_supports_initializing_partition() also checks whether the parent
  partitioning system is content now.

12d359b85a * Removed write_link from the FS module interface. Adjusted all FS
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!).

1fbe3ccd4e * Reformatted to honor 80 chars/line limit.
* Renamed a few parameters of the FS module hooks:
  - *file in the attribute functions to *vnode
  - v to vnode
  - I could barely restrain myself from renaming the "_*" parameters. I
    understand this marks return parameters, but I'd prefer a nicer prefix
    or suffix (that doesn't makes you think this is a private/internal
    identifier) like "out", "ret", "return", "result", or something similar.

I'd also like to propose renaming {read,write}_link() to
{read,write}_symlink(). Er, and do we need write_link() at all?

97e069713b Added a "reenter" parameter to the {read|write}_pages() functions to give file
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).

5207cc7a8c Proposal for a replacement of the notify_listener() and
send_notification() interface, which I personally find quite ugly.
Each notification type gets its own function, which makes very clear,
which parameters are to be supplied. Also note the addition of the
`name' parameter for the `entry removed' notification and `fromName'
for `entry moved'.
