    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:

    @ 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,
    ...
    };

  • 5b37717a2   uwb: improved MAS allocator and reservation conflict handling ... Browse Code »

    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.

  • 6fae35f9c   uwb: add basic radio manager ... Browse Code »

    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.

  • cae1c1141   uwb: reference count reservations ... Browse Code »

    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.
