  • f139caf2e   sched, cleanup, treewide: Remove set_current_state(TASK_RUNNING) after schedule() ... Browse Code »

    schedule(), io_schedule() and schedule_timeout() always return
    with TASK_RUNNING state set, so one more setting is unnecessary.

    (All places in patch are visible good, only exception is
    kiblnd_scheduler() from:

    drivers/staging/lustre/lnet/klnds/o2iblnd/o2iblnd_cb.c

    Its schedule() is one line above standard 3 lines of unified diff)

    No places where set_current_state() is used for mb().

  • 2e124b4a3   TTY: switch tty_flip_buffer_push ... Browse Code »

    Now, we start converting tty buffer functions to actually use
    tty_port. This will allow us to get rid of the need of tty in many
    call sites. Only tty_port will needed and hence no more
    tty_port_tty_get in those paths.

    Now, the one where most of tty_port_tty_get gets removed:
    tty_flip_buffer_push.

    IOW we also closed all the races in drivers not using tty_port_tty_get
    at all yet.

    Also we move tty_flip_buffer_push declaration from include/linux/tty.h
    to include/linux/tty_flip.h to all others while we are changing it
    anyway.

  • 191c5f102   TTY: call tty_port_destroy in the rest of drivers ... Browse Code »

    After commit "TTY: move tty buffers to tty_port", the tty buffers are
    not freed in some drivers. This is because tty_port_destructor is not
    called whenever a tty_port is freed. This was an assumption I counted
    with but was unfortunately untrue. So fix the drivers to fulfil this
    assumption.

    To be sure, the TTY buffers (and later some stuff) are gone along with
    the tty_port, we have to call tty_port_destroy at tear-down places.
    This is mostly where the structure containing a tty_port is freed.
    This patch does exactly that -- put tty_port_destroy at those places.

  • b19e2ca77   TTY: use tty_port_link_device ... Browse Code »

    So now for those drivers that can use neither tty_port_install nor
    tty_port_register_driver but still have tty_port available before
    tty_register_driver we use newly added tty_port_link_device.

    The rest of the drivers that still do not provide tty_struct
    tty_port link will have to be converted to implement
    tty->ops->install.

  • e63f9f747   TTY: bfin_jtag_comm, use tty from tty_port ... Browse Code »

    Switch from mutex to tty_port->lock and to tty refcounting. This needs
    a 'continue' to be added to re-grab a tty after schedule returns.

    And since tty is not protected by bfin_jc_tty_mutex remove it as well.
    But this needs tty_port->count to be protected by tty_port->lock now.

    All num, magic and owner are set by alloc_tty_driver. No need to
    re-set them on each allocation site.

    pti driver sets something different to what it passes to
    alloc_tty_driver. It is not a bug, since we don't use the lines
    parameter in any way. Anyway this is fixed, and now we do the right
    thing.

  • d9d691f58   drivers/tty/bfin_jtag_comm.c: avoid calling put_tty_driver on NULL ... Browse Code »

    put_tty_driver calls tty_driver_kref_put on its argument, and then
    tty_driver_kref_put calls kref_put on the address of a field of this
    argument. kref_put checks for NULL, but in this case the field is likely
    to have some offset and so the result of taking its address will not be
    NULL. Labels are added to be able to skip over the call to put_tty_driver
    when the argument will be NULL.

    The semantic match that finds this problem is as follows:
    (http://coccinelle.lip6.fr/)

    //
    @@
    expression *x;
    @@

    *if (x == NULL)
    { ...
    * put_tty_driver(x);
    ...
    return ...;
    }
    //
