  • a00bfd714   [S390] dasd deadlock after state change pending interrupt. ... Browse Code »

    The dasd_device_from_cdev function is called from interrupt context
    to get the struct dasd_device associated with a ccw device. The
    driver_data of the ccw device points to the dasd_devmap structure
    which contains the pointer to the dasd_device structure. The lock
    that protects the dasd_devmap structure is acquire with out irqsave.
    To prevent the deadlock in dasd_device_from_cdev if it is called
    from interrupt context the dependency to the dasd_devmap structure
    needs to be removed. Let the driver_data of the ccw device point
    to the dasd_device structure directly and use the ccw device lock
    to protect the access.

  • ebc459999   [S390] dasd set offline kernel bug. ... Browse Code »

    The request queue flush function of the dasd driver has to dequeue
    the requests first and then call the end request function. Otherwise
    a kernel bug in ll_rw_block.c might get triggered.

  • 37ab46a3f   [S390] xpram system device class. ... Browse Code »

    Remove system device class for xpram. It creates the directory hierarchy
    under /sys/devices/system/xpram/xpram0. The xpram0 directory is empty and
    it is always created while xpram1 and following devices are always missing,
    independent if the devices exist or not. Since the xpram devices are
    listed in /proc/partitions and /sys/block/ as slram the system device
    class for xpram is meaningless.

  • 5c898ba9d   [S390] xpram module parameter parsing. ... Browse Code »

    The module parameters for xpram are not or in a wrong way parsed.
    The xpram module uses the module_param_array directive with an int
    parameter which causes the kernel to automatically parse the passed
    numbers. This will cause errors if arguments are omitted or cause
    wrong results if arguments have size qualifiers.
    Use module_param_array with charp and parse the arguments later.

  • 34af946a2   [PATCH] spin/rwlock init cleanups ... Browse Code »

    locking init cleanups:

    - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK()
    - convert rwlocks in a similar manner

    this patch was generated automatically.

    Motivation:

    - cleanliness
    - lockdep needs control of lock initialization, which the open-coded
    variants do not give
    - it's also useful for -rt and for lock debugging in general

  • 3d0525954   [PATCH] s390: dasd device identifiers ... Browse Code »

    Generate new sysfs-attribute 'uid' that contains an device specific unique
    identifier. This can be used to identity multiple ALIASES of the same
    physical device (PAV). In addition the sysfs-attributes 'vendor' (containing
    the manufacturer of the device) and 'alias' (identify alias or base device) is
    added. This is first part of PAV support in LPAR (also valid on zVM).

  • 39ccf95e2   [PATCH] s390: dasd ioctl never returns ... Browse Code »

    The dasd state machine is not designed to enable an unformatted device, since
    'unformatted' is a final state. The BIODASDENABLE ioctl calls
    dasd_enable_device() which never returns if the device is in this special
    state. Return -EPERM in dasd_increase_state for unformatted devices to make
    dasd_enable_device terminate. Note: To get such an unformatted device online
    it has to be re-analyzed. This means that the device needs to be disabled
    prior to re-enablement.

    The dasd driver sometimes print the misleading message "Can't offline dasd
    device with open count = 0". The reason why it can't offline the device in
    this case is that the device is still in the startup phase. Print a more
    meaningful message.
