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.

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).

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.

`.'. 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?

This has the advantage that the device can now be access in the right context.

Fixed the calculation of the amount of bytes read in bootfs_read_pages().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8874 a95241bf-73f2-0310-859d-f6bbb57e9c96
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).

_KERNEL_MODE is already defined when using kernel build rules, no need
to do it here manually.

couldn't be satisfied completely (ie. because the file size is not a
multiple of the page size).
It's no longer necessary to implement this functionality in the file systems.

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.

Not yet used - might be used instead of the vm_cache page caching for the file cache.

It still contains a very dump version of a BeOS compatible block cache.

allocate a cache twice.
The VFS is now responsible for allocating the cache object - it will call
the VM to do that if necessary.
Added another accessor call to a pointer to the VFS private vnode object.

allocate a cache twice. Now handles resource shortages gracefully.
Added small description to _vm_map_file().
Minor other cleanup.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@8816 a95241bf-73f2-0310-859d-f6bbb57e9c96
Implemented and added functions from inttypes.h (not everything is working correctly, though).
