79c795cc5d * create_new_vnode() now also fails, if the volume is about to be
unmounted.
* Clarified a comment in fs_mount().
* Added a bit of documentation regarding the mutexes and the basic vnode
  functions.

4f9e4fc932 * The VFS cannot just pass the result of fs_read_dir() calls back to
Userland. It must always set the d_pdev and d_pino fields and, if the
  Entry refers to a mount point even replace d_dev and d_ino.
* Added a TODO comment to entry_ref_to_vnode(). It should take care of
  mount points, as vnode_path_to_vnode() does, I believe. Will verify
  and fix that next.

eab2037630 When a B_CONTIGUOUS area is created, its pages are now reserved upfront, as
this is the one thing most likely to fail - it now also handles this case
gracefully instead of dying.
Small cleanup, cleared some other ToDos: some user functions now delete
the area when they could not copy the target address.

d79751261c Added write support for the cache - it only writes internally right now,
it never writes back dirty pages. Code is not tested!

61b83cc210 * Changed my doxygen comment markers from Qt to javadoc style, still
leaving the tags Qt style though. That's a bit weird, but that's the
  way Axel likes it, and we want to keep him happy, don't we? ;-P
* The common_[path_]read_stat() now fills in st_dev and st_ino in the
  result stat structure after the FS had its go. The information is
  readily available in the VFS, so why bother the FSs. In fact devfs
  didn't (and still doesn't) fill in st_dev which gave dev_for_path()
  some head ache.
* Modified _user_open_parent_dir() to accept a NULL buffer for the
  entry name and added a doxygen comment for it.

df now works properly on Haiku (save that printf() doesn't support
floating point numbers at the moment).

86170a3cd5 * Got rid of devfs_cookie::stream. It was superfluous since one can
always also access it through the devfs_vnode. This also solves an issue
  in devfs_read() where an access of a cookie->stream would crash the
  kernel, since cookie->stream was not set in devfs_open().
* devfs_open() now doesn't fail for directories and symlinks anymore.
  That prevented BNode to work for devfs dirs and symlinks.

1dae20235b If the /..' is /' then the name of the root node should consequently be
`.'. This fixes the _kern_open_parent_dir() syscall for the root directory.

I realized, that rootfs_read_dir() doesn't return the entries `.' and `..',
unlike Be's rootfs. Shall I add those, Axel?

dc3089f8ff Added a "cookie" parameter to the fs_read|write|has_page[s]().
This has the advantage that the device can now be access in the right context.

2829b349c6 Added a "cookie" parameter to the vfs_read|write|has_page[s]().
Added an vfs_get_cookie_from_fd() call to at least temporarily support the
cookie as in the original devfs (not sure yet how this changes).
Implemented vfs_get_file_map() which calls the corresponding FS function.
Moved vfs_get_vnode_cache() around.
vfs_get_vnode() temporarily does its job unlocked - its only to be used (safely)
from within the file cache, but this should definitely be done better.
Fixed a bug in get_vnode_name() - it did not support getting the name of
a root directory; it didn't pass the call through to the parent file system.
Fixed a bug in _user_entry_ref_to_path() which would add another "/" for
files immediately under the root (ie. "df" showed "//boot" as mount point
for the boot partition).

7f2ba8be02 Now clears out any remainders of the pages in the iovecs if the request
couldn't be satisfied completely (ie. because the file size is not a
multiple of the page size).

f363b7231f Eliminated the internal device_info structure - the devfs will now store the
node and its interface directly. It will also convert the old interface into
the new one to simplify the implementation.
devfs_open() now contains the former pnp_devfs_open() as well.
devfs_publish_device() no longer passes the "ident" parameter to its lower
layers - it will be removed.
The VM fs interface has changed to better match the one of the device interface.
