UserlandFS: another 64bit fix.

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


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34147 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented support for the recently introduced I/O request calls
io_request_{offset,length}(), {read_from,write_to}_io_request().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34137 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added support for new notify_io_request() function.

DO_ITERATIVE_FD_IO_{REQUEST,REPLY} were incorrectly categorized by
is_userland_request(), thus triggering a panic()/debugger().

* 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.

* 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().

Added requests for file cache operations. Not used yet.

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.

* Adjusted according to the is_vnode_removed() -> get_vnode_removed()
change.
* The new notification functions are used instead of send_notification()
and notify_listener() now. Mapped them in the BeOS kernel emulation
accordingly. RamFS node monitoring seems to work now.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20298 a95241bf-73f2-0310-859d-f6bbb57e9c96

* More debug output in the kernel module.
* Made publish_vnode() available in userland. For old style FS add-ons
publish_vnode() is used when they request a new_vnode(). The semantics
of new_vnode() changed considerably in Haiku, but publish_vnode()
seems to do pretty much what the old new_vnode() did.
* The UserlandFS hosted RamFS begins to work under Haiku. It runs pretty
soon out of memory though (under vmware with 256 MB) and node
monitoring is broken ATM.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20264 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

First walk through the userlandfs kernel add-on to port it to the Haiku
FS interface. Adjusted old hooks, but didn't add the new ones yet. The
module builds now at least.

Copied userlandfs code from the test tree to the haiku source tree,
where it will be ported to Haiku.
