UserlandFS: Make 64 bit clean and enable build for x86_64.

I did not bother to fix the BeOS kernel emulation, so this part is
still left out of the x86_64 build.

Added public io_request_is_vip(), returning whether the given request has the
VIP flag set.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37678 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added support for in-kernel node monitoring ({add,remove}_node_listener()).

Spotted by "Blub": After unmounting we didn't delete the Volume object.

* For every request to userland we also send the team/thread/user/group ID of
the current thread, now. Implemented by introducing a new base class
KernelRequest which has respective attributes.
* Server: RequestThreadContext does now also save the request that is being
processed. Furthermore some space has been reserved for file system specific
data, which can be initialized by the new
FileSystem::InitRequestThreadContext().
* FUSE library: Implemented fuse_get_context() using the new
RequestThreadContext feature.

Removed the fs_vnode_ops::create_dir() parameter for returning the ID of the
newly created dir. The VFS really doesn't need it and for some file systems
it might not be easy to get by. Several file systems (e.g. rootfs and fat)
were ignoring the parameter anyway.

* Haiku kernel interface emulation: Retrieve the capabilities for each vnode.
We do some caching using a hash table indexed by the operations vector.
* Pass the vnode capabilities to the kernel module.
* In the kernel tailor the operation vectors for volumes and vnodes passed to
the VFS according to the respective capabilities. This way those vectors look
pretty much like those from the client FS. This saves unnecessary calls when
hooks are not implemented and should also fix compatibility problems in cases
where not implementing a hook and returning an error don't mean the same to
the VFS.
* Inlined some of the kernel module Volume class getters.

* Implemented forwarding the do_iterative_fd_io() callbacks to userland.
* Pass the request offset and length with the DoIORequest. This allows us to
already get the first vecs for do_iterative_fd_io() in userland, saving a
trip back and forth.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29546 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The nature of asynchronous I/O is to be asynchronous. So we can't store
an on-stack structure for the request in a hash table when forwarding the
io() hook. Create a new object (HaikuKernelIORequest) instead and store it
in a hash table in HaikuKernelFileSystem.
* Some work on the userland side of do_iterative_fd_io().
* Added some missing requests in UserlandFSUtil::is_{kernel,userland}_request().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29505 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented the userland side for propagating the io() and cancel_io() hooks.
* Implemented io_request_is_write().

A NULL pointer was dereferenced when mounting failed.

More adjustments to the new FS interface. The enabled sources compile again,
but don't link yet.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29332 a95241bf-73f2-0310-859d-f6bbb57e9c96

Some more work towards adjusting the UserlandFS to the current FS interface:
* Split the FSCapabilities bit mask into three bit masks for the FS, the
volume, and the vnodes, since we have three independent FS interface
structures, now. The latter is not supported in the kernel add-on, yet.
* Server:
- Temporarily removed some things from the build (the BeOS interface
and the cache implementations).
- Some WIP in HaikuKernelVolume and [haiku_]kernel_emu.{h,cpp}.
- Added HaikuKernelNode, which wraps fs_vnode for the client FS.
The server is still quite a bit away from being buildable again.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29323 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Renamed fs/vfs_select.cpp to wait_for_objects.cpp and got rid of
vfs_select.h, respectively moved most of it into the new kernel
private header wait_for_objects.h.
* Added new experimental API functions wait_for_objects[_etc](). They
work pretty much like poll(), but also for semaphores, ports, and
threads.
* Removed the "ref" parameter from notify_select_events() and the
select_sync_pool functions as well as from fd_ops::fd_[de]select(). It
is no longer needed. The FS interface select() hook still has it,
though -- the VFS will always pass 0.
* de]select_fd() take a select_info* instead of a select_sync* + ref
pair, now. Added respective functions for semaphores, ports, and
threads.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22416 a95241bf-73f2-0310-859d-f6bbb57e9c96

Got rid of vnode_id and mount_id, replaced with ino_t and dev_t.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21485 a95241bf-73f2-0310-859d-f6bbb57e9c96

The last missing hooks -- get_vnode_name(), write_attr_stat() and
rewind_query() -- are passed to the userland. get_vnode_name() has an
emulation in userland, in case the client FS doesn't implement it.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20522 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented the new attribute open/close/... FS hooks. The mapping to the
old interface is completely done in userland ATM.

It becomes more and more obvious that we probably need to provide
the kernel add-on with a bit more information about what the client FS
interface supports in the first place, so we can save unnecessary trips to
the userland. Opening/closing attributes for a FS using the old style
interface could be handled completely in the kernel add-on, for instance
(even if we lose a bit of accuracy wrt to open modes etc.).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20258 a95241bf-73f2-0310-859d-f6bbb57e9c96

Adjusted the FileSystem, Volume, and UserlandRequestHandler to the new FS
interface. The classes actually interfacing with the client FS add-on still
need to be adjusted.

Class renaming:
UserFileSystem -> FileSystem
UserVolume -> Volume
KernelUserFileSystem -> BeOSKernelFileSystem
KernelUserVolume -> BeOSKernelVolume

The BeOSKernel* classes are indeed intended to handle FS implementations
that use the (old) BeOS FS interface. We'll see how well that will work.

where it will be ported to Haiku.
