    Reintroduce a read-only copy of the devmap features in the device struct.
    This is necessary to solve a deadlock on the dasd_devmap_lock which is
    acquired by dasd_get_features called from the dasd tasklet. The current
    implementation of devmap doesn't allow to call any devmap function from
    interrupt or softirq context.

  • ae6aa2ea8   [PATCH] s390: machine check handler bugs ... Browse Code »

    The new machine check handler still has a few bugs.

    1) The system entry time has to be stored in the machine check handler,

    2) the machine check return psw may not be stored at the usual place
    because it might overwrite the return psw of the interrupted context,

    3) the return address for the call to s390_handle_mcck in the i/o interrupt
    handler is not correct,

    4) the system call cleanup has to take the different save area of the
    machine check handler into account,

    5) the machine check handler may not call UPDATE_VTIME before
    CREATE_STACK_FRAME, and

    6) the io leave path needs a critical section cleanup to make sure that the
    TIF_MCCK_PENDING bit is really checked before switching back to user space.

    Close a small window where a device may be not operational again after senseid
    finished and the "same device" check fails due to dev=0000 by checking for dnv
    after stsch() by then setting the device to not operational. (No need to
    check for dnv in ccw_device_handle_oper() again since we don't do stsch() into
    the subchannel's schib in the meantime and will get a crw anyway if the device
    becomes not oper again).

  • 77933d727   [PATCH] clean up inline static vs static inline ... Browse Code »

    `gcc -W' likes to complain if the static keyword is not at the beginning of
    the declaration. This patch fixes all remaining occurrences of "inline
    static" up with "static inline" in the entire kernel tree (140 occurrences in
    47 files).

    While making this change I came across a few lines with trailing whitespace
    that I also fixed up, I have also added or removed a blank line or two here
    and there, but there are no functional changes in the patch.

    The FBA discipline does not use retries for failed requests. A request fails
    after the first unsuccessful start attempt. There are some rare conditions
    (e.g. CIO path recovery) in which the start of an i/o on a fba device can
    fail. A tiny amount of retries is therefore reasonable.

  • b03efcfb2   [NET]: Transform skb_queue_len() binary tests into skb_queue_empty() ... Browse Code »

    This is part of the grand scheme to eliminate the qlen
    member of skb_queue_head, and subsequently remove the
    'list' member of sk_buff.

    Most users of skb_queue_len() want to know if the queue is
    empty or not, and that's trivially done with skb_queue_empty()
    which doesn't use the skb_queue_head->qlen member and instead
    uses the queue list emptyness as the test.

  • 66a464dbc   [PATCH] s390: debug feature changes ... Browse Code »

    This patch changes the memory allocation method for the s390 debug feature.
    Trace buffers had been allocated using the get_free_pages() function before.
    Therefore it was not possible to get big memory areas in a running system due
    to memory fragmentation. Now the trace buffers are subdivided into several
    subbuffers with pagesize. Therefore it is now possible to allocate more
    memory for the trace buffers and more trace records can be written.

    In addition to that, dynamic specification of the size of the trace buffers is
    implemented. It is now possible to change the size of a trace buffer using a
    new debugfs file instance. When writing a number into this file, the trace
    buffer size is changed to 'number * pagesize'.

    In the past all the traces could be obtained from userspace by accessing files
    in the "proc" filesystem. Now with debugfs we have a new filesystem which
    should be used for debugging purposes. This patch moves the debug feature
    from procfs to debugfs.

    Since the interface of debug_register() changed, all device drivers, which use
    the debug feature had to be adjusted.
