This makes the data = NULL case more consistent to the data != NULL case. The functional change is that now platform_device_add_data(somepdev, NULL, somesize) sets pdev->dev.platform_data to NULL instead of not touching it.

When a device is registered to a bus it will be a) added to the list of devices of the bus and b) bind to a driver (if one matches). As a result of a driver being registered at this bus between a) and b) this device could already be bound to a driver. This leads to a warning and incorrect refcounting. To fix this add a check to device_attach to identify an already bound device. Signed-off-by: NSebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

When certain technologies shutdown their interface without waiting for the acknowledgement from the chip. The receive_buf from the TTY would be invoked a while after the relevant technology is unregistered. This patch introduces a new flag "is_registered" which maintains the state of protocols BT, FM or GPS and thereby removes the need to clear the protocol data from ST when protocols gets unregistered. This fixes corner cases when HCI RESET is sent down from bluetooth stack and the receive_buf is called from tty after 250ms before which bluetooth would have unregistered from the system. OR - when FM application decides to close down the device without sending a power-off FM command resulting in some RDS data or interrupt data coming in after the driver is unregistered.

A kernel booted with no_file_caps allows to install fscaps on a binary but doesn't actually honor the fscaps when running the binary.

next_pidmap() just quietly accepted whatever 'last' pid that was passed in, which is not all that safe when one of the users is /proc. Admittedly the proc code should do some sanity checking on the range (and that will be the next commit), but that doesn't mean that the helper functions should just do that pidmap pointer arithmetic without checking the range of its arguments. So clamp 'last' to PID_MAX_LIMIT. The fact that we then do "last+1" doesn't really matter, the for-loop does check against the end of the pidmap array properly (it's only the actual pointer arithmetic overflow case we need to worry about, and going one bit beyond isn't going to overflow).

Mouse gets "stuck" after restore of PV guest but buttons are in working condition. If driver has been configured for ABS coordinates at start it will get XENKBD_TYPE_POS events and then suddenly after restore it'll start getting XENKBD_TYPE_MOTION events, that will be dropped later and they won't get into user-space. Regression was introduced by hunk 5 and 6 of 5ea5254aa0ad269cfbd2875c973ef25ab5b5e9db ("Input: xen-kbdfront - advertise either absolute or relative coordinates"). Driver on restore should ask xen for request-abs-pointer again if it is available. So restore parts that did it before 5ea5254.

Instead of overloading __blk_run_queue to force an offload to kblockd add a new blk_run_queue_async helper to do it explicitly.

In raid5 plugging is used for 2 things: 1/ collecting writes that require a bitmap update 2/ collecting writes in the hope that we can create full stripes - or at least more-full. We now release these different sets of stripes when plug_cnt is zero. Also in make_request, we call mddev_check_plug to hopefully increase plug_cnt, and wake up the thread at the end if plugging wasn't achieved for some reason. Signed-off-by: NNeilBrown <neilb@suse.de>

When an md device adds a request to a queue, it can call mddev_check_plugged. If this succeeds then we know that the md thread will be woken up shortly, and ->plug_cnt will be non-zero until then, so some processing can be delayed. If it fails, then no unplug callback is expected and the make_request function needs to do whatever is required to make the request happen. Signed-off-by: NNeilBrown <neilb@suse.de>

md has some plugging infrastructure for RAID5 to use because the normal plugging infrastructure required a 'request_queue', and when called from dm, RAID5 doesn't have one of those available.

If we know we are going to punt to kblockd, we can drop the queue lock before calling into __blk_run_queue() since it only does a safe bit test and a workqueue call. Since kblockd needs to grab this very lock as one of the first things it does, it's a good optimization to drop the lock before waking kblockd. Signed-off-by: NJens Axboe <jaxboe@fusionio.com>
