simple_open: automatically convert to simple_open()
Many users of debugfs copy the implementation of default_open() when
they want to support a custom read/write function op. This leads to a
proliferation of the default_open() implementation across the entire
tree.
Now that the common implementation has been consolidated into libfs we
can replace all the users of this function with simple_open().
This replacement was done with the following semantic patch:
<smpl>
@ open @
identifier open_f != simple_open;
identifier i, f;
@@
-int open_f(struct inode *i, struct file *f)
-{
(
-if (i->i_private)
-f->private_data = i->i_private;
|
-f->private_data = i->i_private;
)
-return 0;
-}
@ has_open depends on open @
identifier fops;
identifier open.open_f;
@@
struct file_operations fops = {
...
-.open = open_f,
+.open = simple_open,
...
};
</smpl>

uwb: improved MAS allocator and reservation conflict handling
Greatly enhance the MAS allocator:
- Handle row and column reservations.
- Permit all the available MAS to be allocated.
- Follows the WiMedia rules on MAS selection.
Take appropriate action when reservation conflicts are detected.
- Correctly identify which reservation wins the conflict.
- Protect alien BP reservations.
- If an owned reservation loses, resize/move it.
- Follow the backoff procedure before requesting additional MAS.
When reservations are terminated, move the remaining reservations (if
necessary) so they keep following the MAS allocation rules.

uwb: add basic radio manager
The UWB radio manager coordinates the use of the radio between the
PALs that may be using it. PALs request use of the radio with
uwb_radio_start() and the radio manager will start beaconing if its
not already doing so. When the last PAL has called uwb_radio_stop()
beaconing will be stopped.
In the future, the radio manager will have a more sophisticated channel
selection algorithm, probably following the Channel Selection Policy
from the WiMedia Alliance when it is finalized. For now, channel 9
(BG1, TFC1) is selected.
The user may override the channel selected by the radio manager and may
force the radio to stop beaconing.
The WUSB Host Controller PAL makes use of this and there are two new
debug PAL commands that can be used for testing.

uwb: reference count reservations
Reference counting the struct uwb_rsv's is safer and easier to get right than
the transferring ownership of the structures from the PAL to reservation
manager.
This fixes an oops in the debug PAL after a reservation timed out.
